Is it possible to add validation to a cell such that if it is null an
error/warning message appears? The cell should allow any value to be
entered, it just can't be null.

Thanks!

I don't think so via Data|Validation.

But maybe you could just use an adjacent cell (formatted in nice big bold red
letters):

=if(a1<"","","<-- This cell cannot be empty")

Hi

you can't do it via data / validation - as this only works when someone
enters something into the cell - you could however, put code against a
worksheet_selectionchange, workbook_beforeprint or workbook_beforeclose
event - which ever is the most appropriate that doesn't let them select
another sheet / print or close the workbook without data in a specific
place.
If you'ld like additional information on how to this, please nominate an
event and the cell(s) you want to check.
