this is the formula I have right know (in a seperate workbook)
=SUMPRODUCT((YEAR(A1:A10)=2005*(MONTH(A1:A10)=11)* (C1:C10="H-540")*E1:E10))
this gives me a $0.00 total when I should be at a $3500.00 total
The format for first column I had the month in was general , I tried typing
in the number for the month and the name same result.
I switch the format to Month-Day-Year

Ctrl+Shift+Enter ?? after didn't work either

The problem with having just a separate month column is that there can be
data for say Jan 2005 and Jan 2006, so I added a test for the year.

This should still get you the cost for Jan 2005

=SUMPRODUCT(($A$1:$A$100="Machine
#1")*(YEAR($C$1:$C$100)=2005)*(MONTH($C$1:$C$100)= 1)*$D$1:$D$100)

and this will get the first quarter

=SUMPRODUCT(($A$1:$A$100="Machine
#1")*(YEAR($C$1:$C$100)=2005)*(MONTH($C$1:$C$100)= {1,2,3})*$D$1:$D$100)

where column A holds the machine data, C holds the date, and D the amount.
Just change to suit

Tks for the quick response.
The spreadsheet I'm using is set up like a database.I have 2 columns for
Date. The first only shows the month, the second shows the actual date the
main. was done.
The first column is the one I need (I think).

Here's my question
For the month of January for Machine #1 what was the total cost of
maintenance?

so for every Month in column1 that = January and for every machine #1 =
column 2
sum up all cost .

I'm not sure if it should be treated as an array (I've tried both ways
same
result)

Tks

I need to keep track of maintenance on certain machines and how much
it
costs.
Would like to be able to show how much was spent on each machine in a
given
month or qtr.
