Maybe something like this entered on your Summary sheet in column D:

=SUMPRODUCT(--(Detail!A$2:A$10=A2),--(Detail!D$2:D$10=B2),Detail!F$2:F$10)

Copy down if needed.

I need to summarize by Division/Item # but I don't know how to refer to the
concatenatation (?) of the two fields on the Summary sheet.

Detail worksheet:
- Column A = Division Column D = Item # Column F = Quantity

Summary worksheet
- Column A = Division Column B - Item # Column D = Summary Quantity

Can someone help me with this? Sorry I'm still learning, but the last
help I asked for (LOOKUP) - worked like a charm, so I am emboldened to
ask one more question.

Thanks.
