如果值与来自两个单独列的条件匹配，则对一列中的单元格求和

Question

Please I need some help as I'm having trouble getting this to work. Please see the image below. The result I want is the value in cell B21 for the entire table in the picture. Cell A21 contains one piece of the criteria for the formula. I need to sum the values in column H if the value in column F matches A21 and has the same value in column C or E. For example, the Proj# is the same for cells E2 and E3, and since F2 matches A21, the formula in theory will sum H2 and H3. The result would be 9. I'd prefer a faster processing formula than an array or query

Answer 1

Use Filter and Match:

=sum(filter(H2:H16,isnumber(MATCH(E2:E16,filter(E2:E16,F2:F16=A21),0))+ISNUMBER(MATCH(C2:C16,filter(C2:C16,F2:F16=A21),0))))

Answer 2

shorter:

=SUM(FILTER(H:H, REGEXMATCH(E:E&C:C, JOIN("|", FILTER(E:E&C:C, F:F=A21)))))
