Kevin,
In my testing (XL2003) I can only enter data from the list when
I select LIST as a DV option; anything else produces an error.

Hi

I want to use data validation and have been looking at the website
www.contextures.com

From here I have used the following formula in my data validation / source
to link to a list and update automatically as new entires to my list are
added / deleted

=OFFSET(RegionStart,1,0,COUNTA(RegionColumn)-1,1)

The problem is it allows me to enter values not in the list (there are no
blank spaces when I select the list) and I would like to restrict this so
that only values on the list can be restricted

Thanks for your help
