Hello. I have this small problem concerning the validation of the values the
users can enter in a table: the source list contains several cells than
aren't usually filled wiith values, therefore the validation treats them as
0. They come as a formula with reference to another sheet, so that's why I
believe the option "Skip blanks" does not work. The problem is some
operations in my table involve the COUNTA formula, and everytime a user
mistakenly enters 0 (from the drop down list created by the validation), this
0 value is counted and messes up my things there. How do I get rid of these 0
values?

Thanks,
Devlin
