I'm trying to validate data that is being entered into a cell based on a
list that is on another worksheet in the same workbook. I have the range
with the list set up on Sheet 3 and the cell I'm trying to validate against
this list is in Sheet 1. I've set up a Defined Name for the Range on Sheet
3. When I set this up in the data validation screen, I pick list and I set
the Source equal to the name of the range. I also ensured that on an error
the program should stop. I can see the list in the pull down menu, but when
I enter data that is not in the list, the error is never trapped. If I put a
list on the same worksheet, the error will trap. Is there something I'm
missing? I'm working with Excel 2003.
