The following formula returns 0.

=SUMPRODUCT(--(YEAR(Requisitions!$C$7:Requisitions!$C$1015)=2009 ),--((Requisitions!$H$7:$H$1015)=RIGHT(A3,5)),--(RIGHT(Requisitions!$G$7:Requisitions!$G$1015)=610 06),Requisitions!$F$7:$F$1015)

C F G H

6/29/2009 $29,466.00 41-70-80801-61006 80801
6/29/2009 $2,080.00 41-70-80801-61006 80806
6/29/2009 $8,840.00 41-70-80801-61006 80801
6/30/2009 $1,061.16 41-70-80801-61006 80804
7/1/2009 $4,433.90 41-70-80801-61006 80801
7/6/2009 $20,000.00 41-70-80801-61006 80801

The following works well with the 3rd variable of column (G) not being used

=SUMPRODUCT(--(YEAR(Requisitions!$C$7:Requisitions!$C$1015)=2009 ),--((Requisitions!$H$7:$H$1015)=RIGHT(A3,5)),Requisit ions!$F$7:$F$1015)

Your help is appreciated.
