Is Column B a real date formatted to look like mmm/yy or is it text
consisting of the 3-letter abbreviation for the month followed by a slash
followed by the 2-digit year?

Can you clarify what is in Column D? You have what appears to be 2 names
separated by a comma/space, but your question only mentions the first listed
name. Are you looking for a partial match (nameA in the cell even if there
are other names) or a full cell match (nameA when only nameA is in the cell;
no match if there is a second name coupled with it)?

Column B = mmm/yy
Column C = Quanitity
Column D = Criteria (nameA, nameB)

I would like to sum column C for all quantities which match citeria in D
(nameA) for a certain month and year (Dec, 2007). I tried unsuccessfully
to
use an IF statement for column D and a sumproduct for the remainder of the
formula criteria. Any assistance would be much appreciated.
