Hi, I am still having an issue with a somewhat complex data retrieval/lookup
process. Thanks to those who have tried to help.

I am setting up a Workbook that tracks royalty reports for 3 dozen licensees
we work with. I am outputting data from our accounting system to a worksheet
and I want to look up the sales revenue for each licensee and copy/retrieve
that data into the template. The problem is, there are multiple licensees
with multiple product types, and in some cases, the same product type is
listed more than once for a given licensee:

I have tried doing this with an INDEX/MATCH that is "mostly" working:

{=INDEX(QBData_Feb!$I$4:$I$500,MATCH(1,($A13=QBDat a_Feb!$B$4:$B$500)*(O$4=QBData_Feb!$C$4:$C$500),0) )}

The problem is, the index/match is only returning the first value it finds
for the specified condition when often there are several instances where more
than one value needs to be found. In the above example, $A13 and O$4 can be
found in the data table more than once, so I need those records summed.

My data looks like this:

DataSheet: QBData_Feb
DataRange: QBData_Feb!A:I
Lookup/Template Sheet: Royalty Report (Feb07)
Lookup Criteria1: various licensees in column A
Lookup Criteria2: various product types in row 4

Any thoughts on how I can return the sum of several records would be
appreciated. Thanks!
