Try this one:
=IF(ISERR(F37/SUM(F37:F38)),"-",F37/SUM(F37:F38))

I have the following formula in cells for future months. I would like to
hide he divo result for months wihout data.

my formula is =F37/SUM(F37:F38)

I tried to enter this as =IF(ERROR(F37/SUM(F37:38)),"-",F37/SUM(F37:38) as I
found in online help. This formula does not work either.

Can anyone give me the correct formula to hide the divo error message for my
formula?
