I need to count the number of rows of data that match the following criteria:

The columns of date include:
Column A - Year i.e. 2006
Column B - Y or N
Column C - Y or N

Need to count number of rows where year = 2006 and either Column B = Y or
Column C = Y.

So far I have: =SUMPRODUCT((A2:A100=2006)*((B2:B100="Y")+(C2:C100 ="Y")))

This seems to work correctly if either column B or C are Y but will
overcount if they are both Y. Any ideas. Thanks.
