That doesn't tell us much without knowing what is in H20 and G20 for each of those.

BTW: Is it possible H20 contains " " a space, instead of being ""

I ask because you said this in post #1
=IF(COUNT(H20)<>1," ",IF(H20<=G20,"Yes","No"))

In any event - that formula should be: =IF(COUNT(H20)<>2,"",IF(H20<=G20,"Yes","No"))
