This formula is summing ALL the incidences in the N column of what's in
E2. I
want it to sum ONLY those that are in E2 but also also matching what's in
A3.

=SUMPRODUCT(--(Data!$E$3:$E$5000=$A$3)--(Data!$R$3:$R$5000=E2),Data!$N$3:$N$5000)

I can't figure out why it's not working, because a similiar formula works
for other situations.

Thanks,

Steve
