OK, next step.
These two formulas work separately and produce my desired result:
=IF(G110>0,SUMPRODUCT(--(D110

112>0),G110:G112,'ROI
Questions'!B35:B37))+(D114/E114)*G114
=IF(G110<0,D110/E110*G110*-1+SUMPRODUCT(--(D111

112>0),G111:G112,'ROI
Questions'!B36:B37))+(D114/E114)*G114
But when I combine the two IF statements as below, I get a VALUE error.
Where is my error?
=IF(G110>0,SUMPRODUCT(--(D110

112>0),G110:G112,'ROI
Questions'!B35:B37))+(D114/E114)*G114,IF(G110<0,D110/E110*G110*-1+SUMPRODUCT(--(D111

112>0),G111:G112,'ROI Questions'!B36:B37))+(D114/E114)*G114
Also, in the two independent formulas in the first part of this question
above, before combining the two IF statements, I don't understand why the IF
statements don't need a closing paranthesis to end each formula. This is a
new one to me.
