It's best to assign specific cells to contain your variable criteria, so
that you don't have to change the formula itself when the criteria changes.

With say desired date entered in E1, and desired category entered in F1,
try this:

=Sumproduct((A2:A25=E1)*(C2:c25=F1)*D2:D25)

Can I add an additional criteria to this formula? For instance, can I say
sum
if category is Events and date is 1/1/09?

With category in C and Amount in D use SUMIF

=SUMIF(C:C,"Events",D:D)

I want to have a cell that is calculating all costs in a particular

The data is laid out in rows, so I will have the following columns:

Date Vendor Category Amount

I want a cell that is adding all amounts that are listed as a particular
category. One category might be "Events", another "Operations", etc. I
want
these totals to be separated per category.
