See the screenshot below. What function can be used in cell G3 (and then copied through the range G3: L9) to summarize the total number of units sold by month and salesperson? Assume that the three columns of the dataset have been named Name, Month, and Units_Sold. = SUBTOTAL(9, Units_Sold, Month, Gexist2, Name, existF3) = SUBTOTAL (9, Units_Sold, Month = Gexist2, Name = existF3) = SUMIF(Month, Gexist2, Name, existF3, Units_Sold) = SUMIF(Month = Gexist2, Name = existF3, Units_Sold) = SUMIFS(Units_Sold, Month, Gexist2, Name, existF3) = SUMIFS(Units_Sold, Month = Gexist2, Name = existF3) =AUTOSUM(Units_Sold, Month, Gexist2, Name, existF3) =AUTOSUM (Units_Sold, Month = Gexist2, Name = existF3)
