Counting cells against conditions in 2 columns

I run Excel 2002 in Windows 7.  
I have a sheet which grades many examples of 3 items (called A B and C, say) into 3 grades (1, 2, and 3). Each example gets a new row.
Col A contains the Item name, Cols B-H contain other data, Cols I-O contain tests and Col P contains the calculated grade for that example.
I need to count how many examples of Item A in Col A are graded as a 3 in Col P, etc.
Could someone guide me?
Thanks in advance
Tony

If I'm not mistaken, after reading again you question, this is the formula that you want:

=SUMPRODUCT((A:A="A")*(P:P=3))

It will count how many items "A" you have on column A that have a grade "3" in column P, right?

If you just want to count the number 3 in column A, you can use a simple COUNTIF():

=COUNTIF(A:A,3)

If you want to count using multiple criterias, you need to use SUMPRODUCT() function, like this example:

If you post a sample data, I can give you a more realistic answer.

In Excel 2002 you need to use a fixed range for SUMPRODUCT (not the whole column) so you'd need to revise jppinto's suggestion something like this

=SUMPRODUCT((A$2:A$100="A")*(P$2:P$100=3))

extend ranges as required

Thanks very much. Exactly what was needed.  And thanks in particular for reference to the simple article on the use of SUMPRODUCT which, for me anyway, has always been the hardest function to understand.
