Ok, this has been a very helpful forum so here goes another.

I have 3 columns D2 (with a date ie 20 Aug 09), F2 (with a date or not ie
22
Aug 09 or blank), and G2 which is the total days between the 2 dates (2
days). The formula below is what gives me the total days, but in F2
without a
date, it gives me a negative number. I don't want any number to appear
there
if F2 is blank. Help

=DAYS360(D5,F5,FALSE)
