It would help if you were to post your formula and tell us what cell
(s) you are using, but generally you need to do something like this:

=IF(dob="","",your_existing_formula)

where dob is the cell that contains the date of birth (or is empty).

Hope this helps.

Thanks for any help anyone can give me on this...
