Sorting Merged Cells Of Differant Sizes

Hi all.

I have set up a workbook that is sent out to lots of different users. They each keep and use their own copy.

I have set it up so that everything looks OK and is visible on MY screen, but I'm conscious that some users may have different screen sizes, different toolbars set up, and so on, which might make some parts not immediately visible to them.

I have set up an auto-execute macro which automatically sets the zoom factor to best fit, for several of the worksheets, and this works fine.
Here's the code that does it.
Code:

Sheets("WELCOME").Select
    Range("A1:N18").Select
    ActiveWindow.Zoom = True

By repeating this code for each worksheet, I can make each one be zoomed just right.

However, the file contains 8 sheets that are all identically laid out, except the number of rows is different.
What I want to do is go to the worksheet that has the largest number of rows (it's always the same worksheet, so I know which one it is), set the zoom factor for THAT worksheet (which I can do, and it always has the same number of rows), and then take THAT zoom factor, whatever it is - and it will vary depending on the user - and apply that to the other worksheets that have a similar layout.

I could just go through each worksheet and zoom it automatically, but that would mean that some of the sheets looked very large, others very small, and I'd like them to have a consistent appearance.
I could also specify a range on each worksheet that was similar to the appropriate range on the longest worksheet, and zoom that automatically, but that's not ideal either, because some of the row heights vary from sheet to sheet, and again I'll end up with different font sizes.

Anyone know how to do this ?

I'm trying to have separate column widths in the same column, based on the rows.

the top half of my spreadsheet are assumptions, formatted with the corrects widths needed, but then below I have calculations and such that I do not want the same widths for. how can I lock in the top part so I can decrease the column widths for the bottom half of my spreadsheet?

hope this makes sense.

Is there an on error exit sub command. I would like my Macro to just stop running if there is an error instead of an error message popping up. Thanks in advance

I need to lock consecutive rows together before sorting. e.g. A1 contains a name and A2 is blank: B1 contains data related to name in A1 - so does B2, and so on. Therefore need to lock rows 1 and 2 together, then 3 and 4 together and so on, but sorting on the data in the first cell of the group e.g. A1

I have a merged cell which contains a text with multiple lines.
I want to split the lines into multiple rows.Each line should come in a different row.
I want to do this using macro.Is there is anyway to do this?
There is an option to split the cell into multiple cells on the basis of the delimiter, but there is no option to split them into rows.
