SumProduct Formula with Multiple Criteria

I have a spreadsheet with a budget and by month by product. I am trying to use the Sumproduct Formula to calculate the YTD budget based on 2 criteria. I've looked at others formula's and i cannot seem to understand why my formula isn't working.

Here is how i have it laid out:

Column c6:c14 = Product
column d5:05 = Month (January, February, March... )
Begining in column d6:o13 i have the data that i am trying to sum. For instance if June, i want is to sum everything less than June so May - Dec. for a particular product. Here is my formula.

=SUMPRODUCT(('YTD Volume Pivot'!$C$11:$J$11=$C27)*('YTD Volume Pivot'!$A$12:$A$27<$D$5),'YTD Volume Pivot'!$C$12:$J$27)

PLEASE HELP. I am getting desperate.
