Hi everyone, this is my first post here. I consider myself a more advanced Excel user and can navigate my way around fairly well. I've written a spreadsheet and am wondering if there is a way to permit data entry in a cell, contingent upon another cell being populated.
In simple terms, you can't enter data in cell X, until cell "Y" has been populated with something.
Can anyone help with this, because I can't figure it out....
