I tried to reproduce the error and it is possible that A4 does not match
anywhere in Row#2 or the Raw Data worksheet.

Hello,

Can someone tell me why this is not working or do I need to provide more
information? I'm getting a #N/A error. I think it is related to the second
"Raw Data statement in parentheses). Thank you.

=SUMPRODUCT(('Raw Data'!$B2:$B25079=$B4)*('Raw Data'!$T2:$T25079=$D$2)*('Raw
Data'!$M2:$M25079=I$2),OFFSET('Raw Data'!$D2:$D25079,0,MATCH($A4,'Raw
Data'!2:2,FALSE)-4))
