Thanks Don, but this returns the same result and does not ignore the
quantity
that was received.

I'm trying to calculate monthly inventory usage from data retrieved
from
daily usage reports. The formula below works, but not sure how to
ignore
rows
with receiving data. Column "C" includes notes and I would like to
ignore
in
my calculation all rows with the note of "Received against PO". How
can
this
be accomplished?

The formula I'm currently using is...
=SUMIF($H$2:$H$100,"1/2009",$D$2:$D$100)

Column "H" has the month/year and column "D" includes both usage and
receipts.

Thanks in advance!

Brian
