Try this:

=IF(OR(D9="",E9="",F9=""),"",INDEX(MATCH(F9-E9,BWP!A1:A45,0),MATCH(D9,BWP!A1:AO1,0))

When referencing a range on another sheet it's not necessary to repeat the
sheet name:

BWP!A1:BWP!A45

BWP!A1:A45

Instead of displaying A8, how would I go about getting this to display
what
is contained within A8? What would I replace the ADDRESS function with? Or
what would I add on to make it display the value instead?
