Any error in my SUMPRODUCT formula ?

[Tufail]

Hello All,
I want to know if some error in my formula, I am using 2 list 1=SaleList
2=PaymentList and wanted bring payment clear date from PaymentList into
SaleList, exp is as under :

PaymentList
A_1[Status] E_1

           Y_1 [Date]
Receivabe              100              20-May-2009
Clear                     100              25-May-2009

=IF($AS1="Clear",SUMPRODUCT((PaymentList!$E$1:$E$5000=$F1)*(PaymentList!$A$1:$A$5000="Clear"),(PaymentList!$Y$1:$Y$5000)),$B$4))

This formula is in SaleList as well $AS1, $F1 & $B$4 are in SaleList too,
$B$4 cell has current date, means if not clear status in PaymentList then
come out current date and it's working but if status clear in PaymentList
then came out #N/A error !, hope I explained well.

Thanks in advance.
