I tried to return a value in sheet1, column A (vertical), to sheet 2 (Horizontal format), if the "Process_Step" and "WO" is matched. As the data is huge and there're many columns, I do not know how to specifically to use the index and match or vlookup, to return the column A value (Date) if the criteria are meet. The INDEX formula I written, is not working as I understand it's not making sense to Excel. [=IF(INDEX(WIP!$A$1:$W$8835,MATCH($B3,WIP!$U:$U,0),MATCH(C$2,WIP!$L:$L,0)),C3=WIP!$A:A,"")]
