My data is arranged in three columns: Col a is my inventory
count date, Col b is a code letter (a,b,c or blank), col c is my
sales.
col a col b col c
s04 a 10
f04 b 12
s05 c 13
f04 a 10
s04 a 12
f04 (blank) 9

I need to sumif all numbers in column c where column a and
column b match (for example: col a has 2 s04 where col b has
an A so I need the total of 10+12. I suppose I could
concatenate A+B, and then sumif on that, but is there a
better way? Thanks for any help.

Here's a link to a recent discussion of that very same topic:
http://groups.google.com/group/microsoft.public.excel.misc/browse_thread/thread/e0d563106f3d908f/98aed4413d44708e?q=%3DSUMPRODUCT(--(A1%3AA10%3D%22x%22)%2C--(B1%3AB10%3D%22y%22)%2CC1%3AC10)+&rnum=1#98aed4413 d44708e

try
=sumproduct((a2:a200="s04")*(b2:b200="a")*c2:c200)

Try something like this:

D1: =SUMPRODUCT((A1:A100="s04")*(B1:B100="a")*C1:C100)

Change range references to suit your situation.

Does that help?

Ron and Don,
