I have a column of values that I would like to calculate the sum product with a second column depending on what string is in the second column.
i.e. if the second column has the string "estimate" I would like to multiply the value in the first column by 0.6. if the second column has the string "calculated" I would like to multiply the value in the first column by 0.9 if the second column has the string "weighed" I would like to multiply the value in the first column by 0.97.
and then sum all of these values together.
I have made a start:
=SUMPRODUCT(J5:J27*(IF(ISNUMBER(SEARCH("Estimate",M5)),0.6,IF(ISNUMBER(SEARCH("Calculated",M5)),0.9,IF(ISNUMBER(SEARCH("Drawing/Weighed",M5)),0.97)))))/$J$29
However this only changes the sum product based on the contents of M5 and not each row in turn.
Cheers!!
