Hi-
The following array formula is working for me:
=(SUMPRODUCT(--(D9:D55>DATEVALUE("12/31/2006")),(--(D9:D55<=K1)),E9:E55))/(COUNTIF(D9:D55,">12/31/2006")-COUNTIF(D9:D55,">5/31/2007")).
However I would like for 5/31/2007 to be a cell reference of K1. I want to
be able to change just K1 each month. I can not get this to work with a cell
reference. Column D has dates and Column E is numbers.
Thanks again.

You didn't say what formula you tried. Was it
=(SUMPRODUCT(--(D9:D55>DATEVALUE("12/31/2006")),(--(D9:D55<=K1)),E9:E55))/(COUNTIF(D9:D55,">12/31/2006")-COUNTIF(D9:D55,">"&K1))
?

I accidentally responded direct on this. So this is a re-response
I'm not sure exactly what this formula is supposed to accomplish, but see if
this helps.
=(SUMPRODUCT(--(D9:D55>DATEVALUE("12/31/2006")),(--(D9:D55<=VALUE(K1))),E9:E55))/(COUNTIF(D9:D55,">12/31/2006")-COUNTIF(D9:D55,">"
& VALUE(K1)))
HTH,
