Hi
understand now ...

try
=SUMPRODUCT(--(A2:A6=F2),--(B2:B6<=E2),C2:C6)

where cell F2 contains the owner and E2 contains the date.

Cheers

Thanks, I'm looking for the running cumulative total by owner by saledate.
so for any given sale date I would like to calculate the cumulative total
up
to that point in time. Any additional Ideas. Thanks.

Hi

not sure what you mean by owner by date (as all your dates for the owners
are different), however here's a couple of ideas:

=SUMIF(A2:A100,1,C2:C100)
will give you the total of amounts for owner 1

=SUMPRODUCT(--(A2:A100=1),--(B2:B100=DATEVALUE("1/1/05")),C2:C100)
will give you the total of amounts for owner 1 for the 1/1/05

or look at using pivot tables to summaries your data in many different
ways
- check out www.contextures.com/tiptech.html for details on how to use
pivot
tables.

I have data as follows: I would like to create a formula that gives me
a
cumulative balance by owner by date -- How do I do that? Thanks.

1 02/01/90 -50.00
1 03/01/90 -25.00
