hello, i need help on a formula.
basically, what i'm trying to do is i have months going across and two rows 1) actual 2) forecast
i want the formula to sum forecast only if there's a number other than zero in the actual.
for example. i will have forecast numbers for the whole year.
but i only have actuals from jan to july. so i want the formula to only add forecast numbers from jan to july.
see attached excel sheet.
thank you!
