Hello,

I have a formula (see below) that will work for rows 2-1000, but once I
change it to look for columns beyond 2000, it will not work anymore... Any
suggestions?

This works:
=SUMPRODUCT(--('Q Info'!$A$2:$A$1000= 'Per Peice'!A9),'Q
Info'!$C$2:$C$1000*'Q Info'!$B$2:$B$1000)

This DOESN'T work:
=SUMPRODUCT(--('Q Info'!$A$2:$A$9999= 'Per Peice'!A9),'Q
Info'!$C$2:$C$9999*'Q Info'!$B$2:$B$9999)
