Lookup Range Error

My goal is to check duplicate record in excel, if yes, i need to replace the entire row which I need to know the cell number before i modify the row. I refer one of youtuber video “How to get cell number from excel” https://www.youtube.com/watch?v=R5-UMlh2EWY .
Im trying to get “CellIndexValue” dropdown but its showing error. Can anyone help me on this?

Hi @Lugkenish,

Have you create output variable for LookUp Range —> CellIndexValue
and if yes then, check its variable’s scope.

Yes, correct. I missed value in LookUp Range. Thank you alot @samir
