OK - Here's the problem.

I have two worksheets named Totals and Data.

In Data there are three columns, as follows:

A:A B:B C:C
Date Desig Amount

The Date column is formatted for DATE (d-mmm-yyyy); the Desig column is
General formatted with a drop-down list to pick from (Water, Sewage, etc.);
the Amount column is formatted for currency.


In the Totals worksheet, C3:N3 contain dates (m/d/yyyy), B6:B17 contains
the row names corresponding to the names in the Data!B:B (Desig) drop-down
lists, and the range C6:N17 will contain the formula I seek.
I'll just work with cell C3 for now.

Let's start off stating that B6 = "Water" and C3 = 10/1/2007

Here is the logic of what I want to do:

IF the MONTH in Data!A:A = the MONTH in C3,
AND the YEAR in Data!A:A = the YEAR in C3,
AND the text in Data!B:B = the text in B6 (Water)
then
SUM the amounts in Data!C:C


Basically, I only want to sum the numbers if the month, year, and designator
match. I thought that this would be easy but it's kicking my but!
