Hi, I'm really struggling with this one. I have a sheet that has a drop-down with options for "Yes" and "No" and I want to perform an INDEX/MATCH function based on another cell in that row, but only if the result of the drop-down in that row is Yes.
The sheet reference for the Yes/No drop down is {App_S}, and the two cells I want to match are {App_Ref} and [Ref]@row - and the cell I want to return is {App_JT}
I have tried variations of the following:
=IF({App_S} = "Yes", INDEX({App_JT}, MATCH([Ref #]@row, {App_Ref}, 0)))
…but I get an "INVALID OPERATION" return?
Please help!
