If and Index Match

emmawallace24

Hi, I'm trying to use an If statement in my index match formula to skip rows that are pulling from a blank to not overwrite them. I want to skip over pulling from the blank demand ID rows and not overwrite the SubTower row. The below formula doesn't work, should I be using IFERROR function?

=IF(ISBLANK([Demand ID]@row, " ",INDEX({SubTower}, MATCH([Demand ID]@row, {Demand Sort}, 0)), "")))

It looks like your parenthesis are off.

=IF(ISBLANK([Demand ID]@row), " ",INDEX({SubTower}, MATCH([Demand ID]@row, {Demand Sort}, 0)))

Hi thanks for the help Paul. This formula worked but it still made the subtower column input blank. I want to keep what is already in the subtower column if Demand ID is blank. Only use index match if demand ID has criteria. should I be using IFERROR or no ISBLANK?

You cannot have manual entry and a formula in the same cell. You will need to put the formula in a different column to maintain manual entry in the Subtower column.
