try
=SUMPRODUCT(--(Sheet1!N5:N9=A11)*(Sheet1!D5:D9),--(Sheet1!N22:N26=A11)*(Sheet1!D22:D26),--(Sheet1!N39:N43=A11)*(Sheet1!D39:D43))

I am surprised you got zero for an answer, I am not surprised you did not
get the right answer.
in sumproduct each array separated by a "," is multiplied together
as such in your equation the first number would have been
[(1 or 0)+D5]*(1or0)*D22*(1 or 0)*D39 other combos similar.
most patterns would have given some value other than zero for a total of all
the combinations.

Please check if your D column actually has numbers and not numbers in text
format

if you just do = dum(D5:D9) what do you get?

When I enter the formula below, the result I get is 0, when it should
be 490

If Cells N5:N9,N22:N26,N39:N43 = A11

THEN SUM

D5:D9,D22:D26,D39:D43

=SUMPRODUCT(--(Sheet1!N5:N9=A11)--(Sheet1!D5:D9),--(Sheet1!N22:N26=A11),--(Sheet1!D22:D26),--(Sheet1!N39:N43=A11),--(Sheet1!D39:D43))

Any ideas?
