INDIRECT formula giving #VALUE error when adding COLUMN() and not sure how to fix..

Hi All,

Hoping someone can help with my ignorance. I've got a sumproduct formula that's giving me issues.

Currently the formula is:

=SUMPRODUCT(--('2012 Schedule'!$B$2:$JC$2<=$A2),'2012 Schedule'!$B$3:$JC$3)

I'd like to update to:

=SUMPRODUCT(--('2012 Schedule'!$B$2:$JC$2<=$A2),INDIRECT("'2012 Schedule'!$B$"&COLUMN(C1)&":$JC$"&COLUMN(C1)))

But, this gives me the #VALUE error and not sure how to fix.

Any help is greatly appreciated.

Thanks,
Cullen
