Hello,
I am trying to use the formula below to sort through data to total an outstanding number of units. i keep getting a "that function isn't valid" message. What am i doing wrong? please help.
=IFERROR(if(row()<>2,INDEX(arrayformula(filter($I2:$I$2,$C1:$C$2<>"",row($C1:$C$2)=max(if($C1:$C$2=C2,row($C1:$C$2),0)))) ,1),0),0)
Thanks,
