As it is, think your formula should work. If it's somehow not returning the
correct sums (or zeros), then the problem could be either that the (some)
zip codes in col C are text numbers, and / or that (some) numbers within the
col to be summed, col AB, are text numbers

One way is to try instead:

=SUMPRODUCT(--(TEXT(Data!$C$2:$C$1500,"00000")="98366"), --Data!$AB$2:$AB$15
00)

This is what I have been trying to use. What I am doing is looking for a
specific zip code in one column when I find it I want the value of another
column to be added to a total.
