Try this:

Using named ranges:

ChoiceA refers to Sheet1 A2:An
ChoiceB refers to Sheet2 B2:Bn
ExpDate refers to Sheet1 C2:Cn
Spinner refers to Sheet2 A1

Your spinner in linked to Sheet2 A1 and returns a year number like 2007,
2008, 2009 etc

Sheet2 B1 = header = Choice A
Sheet2 C1 = header = Choice B

Enter this formula in Sheet2 A2:

=DATE(Sheet2!A$1,ROWS(A$2:A2),1)

Enter this formula in Sheet2 B2:

=SUMPRODUCT(--(ChoiceA="x"),--(MONTH(ExpDate)=MONTH(A2)),--(YEAR(ExpDate)=Spinner))

Enter this formula in Sheet2 C2:

=SUMPRODUCT(--(ChoiceB="x"),--(MONTH(ExpDate)=MONTH(A2)),--(YEAR(ExpDate)=Spinner))

Select cells A2:C2 then copy down to row 13.

Select the range A2:A13
Goto FormatCellsCustom
Enter mmm for the short month name format or mmmm for the long month name
format
OK out

I have something similar to the above except with 2500 rows. I am looking
to have on a second sheet a count of the number of ChoiceAs and the number
of
ChoiceBs that expire for each month of the year.

(To complicate matters I have a spinner for the year so you can change the
2008 to 2009 and see the expirations in 2009).
