I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).
Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.
For example, suppose you have tables of data on 3 different tabs, all having the same headings. Suppose one of the headings is "gender". If you apply a filter to the table on Sheet 1, to only show the rows containing the word "female", is it possible to have the tables on Sheets 2 and 3 automatically update to only show the "female" rows? Or would you have to manually update the filter criteria in Sheets 2 and 3?
I hope this makes sense. Thank you in advance for any help.
lets suppose my numbers a 1,2,3,4,5,6,7,8,9,10,11
I want to generate all possibilities of the 6 numbers. But i dont want duplicate series.. I mean 1,2,3,4,5,6 and 6,5,4,3,2,1 are duplicates.

Every so often when I attempt to save a file, (including save as), Excel won'r let me. By won't let me I mean:
using Save doesn't appear to do anything using Save As doesn't either do anything, the dialog is not displayed and if I am doing via the File menu then the File menu is exited and the previous ribbon tab is displayed (i.ethe one I was on before clicking 'File') if I close the workbook I am prompted to save, close without saving or cancel. Clicking save just invokes the same msgbox again. I can't work out when it goes into this mode. Some days I can work without this problem, other days I encounter this 2 or 3 times.
The only thing I could suspect was I think this started around about the time I installed xlDennis' code library. I have uninstalled the addin and so far so good, but I cannot categorically say that this was the cause.
Anyone have any idea?
Cheers

Doesn't seem to cover the issue I describe
worksheet. The first column of the table is a list of numbers. I tried
converting the table into text with manual line breaks and tab stops to
divide columns and rows, but that didn't solve my problem.
Excel pastes the data into several rows. When I try to merge them, I
get a warning that the selection contains multiple data values, and
merging into one cell keeps the upper-left most data only.
What I tried that didn't work:
* Formatting the Excel cells as text before pasting the data.
* The various options for "Paste Special." The closest I got was
inserting the table as a Document Object, which could be a workaround,
I guess.
What I am saving for when all else fails:
* The obvious solution of copying row by row into one Excel cell.
The data in the table is information about my dad's medications. I
would like to have reference charts of how to identify the strength of
each tablet by its color and markings. I got the info from the
manufacturers' websites and entered it into tables in Word, which I
would like to copy into a more comprehensive file I am creating in
Excel. The first column of each table is the strength of the tablet,
entered as 1 mg., 2 mg., etc. The subsequent columns describe the
shape, color, and markings. There are 3 tables, each with about 4-5
rows.
Is there a way to copy each one - whether as a table or as text - into
a single Excel cell without losing data?
Many thanks.
I want to combine data from several worksheets into one worksheet.
For example, I have data in Sheet1 (Columns A,B,C), data in Sheet2 (Columns A,B,C), data in Sheet3 (Columns A,B,C) all with varying amounts of rows. (All the rows contain text data).
I need to combine all of the data from the 3 sheets into a single sheet, Sheet4 (Columns A,B,C), eliminating the empty rows.
I've been looking into this for a while, and can't find anything that really helps. Anyone got any pointers of what to look into?
Any help will be beautiful.
Cheers

I have a userform with frames containing textboxes. The user enters a currency value and once they leave the control, then a protected textbox next to it shows the corresponding value in SEK. I started off using the exit event but ran into 2 problems.
If you tabbed out of the last textbox in the frame, the exit event never kicked in (this is documented in other topics but took some time to find). This resulted in me using the exit event for all except the last textbox in the frame that used afterupdate instead I then discovered that the exit events didn't kick in if, instead of tabbing out of the field, I deliberately placed focus in a control elsewhere on the form. Changing the event from exit to afterupdate corrected this. My question then is ... could you guys document in this topic when you would/must use the exit rather than the afterupdate event (or vice-versa).
Thanks
My goal is to drag and fill (or paste) in a colum with a range of rows wiht some hidden (filtered out) rows, and have the filtered out data be unaffected, if that makes sense.
Thanks!

On excel, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get the SAME result of 462,534.05.
I have to account for the difference of not dividing equally so there is some format or accounting function that's preset that I don't want but I have no idea how to fix it or format my excel sheet to calculate as my calculator would.
Please can someone help? Thanks!
bring up a menu anymore. It happens only when I'm in Excel only... it still
works even if I bring up macro editor within Excel... it only doesn't work
when I'm in Excel. I've tried Options and Customize... nothing there seems
to work...
HELP!!!
emailed to me by a co-worker. It's an existing file so I don't know what
restrictions were placed on the workbook. What can I do to fix this problem?
I am working with an Excel spreadsheet and saving it as a .csv file in order to upload to an application that parses out the .csv data as transactions. The system requires .csv files, so this is how I need to save my doc (with this extension). I have been successful at preventing Excel from coverting that long number into scientific format. I have saved as a TXT file, pasted the longer number and it displays correctly. That is all good. But I have to save as a .csv. So if I do that, close the Excel window, and then open again (as the .csv file), the numbers are back to being displayed in scientific format. I have tried creating an Excel doc from scratch and entering text in Text format, to see if this created a cleaner file. But again, the second I save as .csv, close the window and then open that file up again, that dang scientific format is back.
Does anyone have any idea of how to work around this? Once I have successfully gotten the numbers to display as the long-chain number, how can I get them to "stick" so that they don't revert back to scientific format when I reopen the file?
Thanks so much for your help!

I have been tasked with introducing userforms into an excel sheet and tbh I'm quite amazed that excel has this capability of adding userforms to excel sheets.
Anyway, I have 2 columns of data in an excel sheet and I wish to add this to a userform so that the userform displays the 2 columns beside each other with headings, like a table. The user should then be able to select a particular row and insert it into the specified cell.
I would also like the user to select a row on the table and then be able to bring up another table depending on the row selected...basically so that the user can draw deeper into the information that they require.
I have an example excel sheet where I have 2 sheets. One sheet is the user entry sheet called User Entry Screen. the next sheet is the tables sheet where my tables are held. Once the user selects the cell shown in the example sheet, it should then bring up the user form. the user then, depending on which item clicked, then gets shown the next window with a table and info on it. then user should then be able to select an item and the cells on the user entry screen would then get populated.
Personally I think this is a really tricky challenge and any help with doing this would be extremely appreciated.
I'll post up further comments as I am trying to work my way through it!
Thanks,
Jag
display rows that have values greater than 0 in any one of those three
columns. So far I can only filter progressively. If I filter column E and
then filter column G, the second filter is only applied to the results of the
first filter.
Does anybody know if it's even possible to do what I'm trying to do?
I am using Excel 2007 and suddenly I can no longer filter by color. The option is greyed out and so is the sort by Color option. Does anyone have any idea why this would happen?
Thanks in advance.
I've had a long search through your pages to see if this question has been answered before but having browsed through about 50 pages worth of threads I couldn't see anything, but if I am repeating prior information I do apologise.
I've written a macro that is relatively simple. It just takes some information in one format, rearranges it, adds some formatting and performs some calculations. Nothing incredibly fancy but it works fine on my computer.
Now, I need to share this macro with some other people, so basically I've just sent that excel file on to the people that need to use it. Should be fine and in most cases it is, however there is one user who although they can open the file, can't seem to get the macro to run properly.
It seems to get a small way through the macro but then stop with no error messages or any sign that it hasn't completed properly.
I have checked Macro Security level and that is the same as mine, Tools - Add-Ins is the same, In Visual Basic, Tools - References is the same as mine. It is the same Operating system and the same version of Excel.
I have even signed into this person's computer as myself (it's a big company network thing) and tried to run the macro and it works fine, so there is nothing wrong with the hardware.
I've googled and searched and tried everything I can think of but I'm no closer to solving this problem, so if anyone has read through this wall of text and can come up with a possible solution, that would be greatly appreciated to save me from tearing ALL my hair out!
Thanks very much for your time.
I have a question regarding filtering of columns, hopefully someone is able to put me on the right track. I have set up Excel 2007 so that I can click on the drop-down menu in each column to filter them.
However, in my data set there is one blank row separating two set of rows. Now, when I apply the filter on a column, all the rows above the blank row filter correctly, but all the rows below stay un-filtered.
I guess Excel only looks at the consequtive rows, then stops when it hits a blank row. Is there any way of applying the filter beyond a blank row (i.e. the whole column)?
Any advice is higly appreciated.
