I am trying to sum the net sales for the current month in my "Daily Sales Activity" sheet IF my helper column says "YES" (this is the current month) but I keep getting INVALID DATA TYPE.
My formula is =SUMIF([CURRENT MONTH HELPER 2]:[CURRENT MONTH HELPER 2], "YES", [Net Sales]:[Net Sales])
i think its because the rest of the column isn't filled out yet and says INVALID DATA TYPE but that wont be filled out until the days go on. How can I fix this?
