You can use this to compute the sum of col B for dates in col A falling in
Apr 2010
=SUMPRODUCT(--(TEXT(A2:A100,"mmmyyyy")="Apr2010"),B2:B100)
Adapt to suit. I prefer to use the above as I don't have to recall what date
is the last day of the particular month/yr (30th?, 31st? ugh)

I need some assistance with tracking my commissions that are due to be paid
each month. The "Comm Due Date" is in column "C", rows 3 - 30 which list by
date all of the Commissions Due to be paid and the "Comm Balance" is in
column "H", rows 3 - 30 which has the Commission Balance due for each sale.
I tried utilizing a formula from a post that I found from April '05 but for
some reason I keep receiving a #NAME? error. I'm not sure what I am doing
wrong. I want to find the total due by month so that as I add additional
sales to the spreadsheet it will update the total due for each month. Can
anyone please help me?

=SUMIF(Comm_Due_Date,"=04/01/2010",Comm_Balance)+SUMIF(Comm_Due_Date,"=04/30/2010",Comm_Balance)

If you need additional information, please let me know.
