Can you copy/paste your exact formula?
Also, have you verified that all dates are actually entered as dates?

Criteria would be in cells F2 for date (entered as mm/1/yy), F3 for product,

=SUMPRODUCT(--(YEAR(A2:A500)=YEAR(F2)),--(MONTH(A2:A500)=MONTH(F2)),--(B2:B500=F3),--(D2:D500=F4),(C2:C500))

I have an inventory list where different people check out certain products.
I need to be able to have a formula that adds the value of a certain
product
for a certain salesman. This is an example of what I have.

Date Product Amount salesperson
10-Oct Pencil 5 Jacob
15-Oct Pen 10 Brian
16-Oct Paper 2 Brian
20-Oct Pencil 11 Jacob
25-Oct Pencil 7 Brian

and i want it to show that for this month Jacob sold a total of 16
pencils.
