Hi,

I am using data validation formulas under the "custom" drop-down" heading to
control the allowed input into a given cell. However, I also wanted to
include in the expression a constraint that would not allow an entry until
the previous cell had been filled as well. It seems that when I add
"NOT(ISBLANK(B3))", "ISTEXT(B3))" or any other entry to my formula
controlling C3, i.e.
"=AND(ISTEXT(B3),C3=DATE(2008,1,1),C3<=DATE(2012, 12,31))", the formula
stops activating the Error Alert and allows me to enter anything I want.
Any thoughts on why the formula would stop performing once I reference a
cell other than the one I am making an entry in?

Thanks in advance for the help,

Brian

=AND(ISTEXT(B3),C3=DATE(2008,1,1),C3<=DATE(2012, 12,31))

Uncheck the "ignore blank" check box

Thank you so much for the help! That seemed to have done the trick. Been
working with this off and on for days and couldn't get it to work! Thanks
again!
