i need to combine 2 arguments in a SUMIF function so i can use it with Excel
2003. i'm basically trying to make it so a SUMIFS script i wrote will work in
earlier versions of Excel. here are the 2 SUMIF arguments i need to combine...

SUMIF(B1:B50, B50, F1:F50)
SUMIF(I1:I50, TRUE, F1:F50)

so i need to add the cells in F1:F50 where their corresponding value in
I1:I50 is TRUE, and the corresponding value in B1:B50 = B50.

can someone help??
