Hi Matt
I have never tried SUMPRODUCT with multiple sheets, but I think your problem
is the size of the ranges.
They have to be identical in size for there to be corresponding True/False
responses to be multiplied.
I think you would need to treat each as separate SUMPRODUCT equations and
add them together.
=SUMPRODUCT(--(Southwest!A10:A126=1186),--(Southwest!C10:C126))+SUMPRODUCT(--(Midwest!A10:A124=1186),
--(Midwest!C10:C124))+ etc.
