This formula is returning 0 and I do not know why. The colums are correct in the formula.
What I am trying to do is write a formula that says if the first three letters column B in Portfolio Data are "TRA" and on the same row in column E there is NA Gas, then sum up all of those values that meet that criteris in column V. I am using excel 2002.
=SUMPRODUCT(--(LEFT(PORTFOLIO_DATA!$B$2:$B$19000,3)="TRA"),--(PORTFOLIO_DATA!$E$2:$E$19000="NA Gas"),PORTFOLIO_DATA!V$2:V$19000)
