You are counting occurances based upon TWO criteria, date and value.

Whenever you are faced with more than one criteria, consider using
SUMPRODUCT()

=SUMPRODUCT((YEAR(A1:A1000)=2009)*(B1:B1000=10))


change the year and value as you desire. There is a really good write-up on
SUMPRODUCT in:

Hi there -
Stumped on this one... I want to calculate frequency for items that
meet a certain criteria. In this case, date. I have a bunch of data that
looks like this:

COL-A | COL-B
1/2/09 | 10
1/6/09 | 13
1/8/09 | 10
10/23/08 | 10
2/3/09 | 10
2/9/09 | 10

I want to calculate the FREQUENCY of COL-B data for items that occur in
2009. In the example above, that would be 4 for "10" and 1 for "13".

I'm using this data to create a frequency distribution graph.

thanks in advance!
