Cross referencing for duplicate numbers

We have a Completed Smart sheet of people we have contacted for an ongoing project. Weekly we get a new sheet which sometimes had duplicate names of people we have already contacted. Is there a way to easily search our new sheet for duplicates found from our Completed sheet?

    Hi @Susan Barrett

    You could add a "helper column" into this new, second sheet to check the Name column in the Completed sheet and see if the same name appears.

    Try a cross-sheet formula like this:

    =IF(COUNTIF({Name Column Completed sheet}, [Name Column]@row) >=1, "In Completed Sheet", "No Duplicate")

    This says, COUNT if the name in this row is present in the Completed sheet's column. If it is (if the COUNT is equal to - or greater than 1), return "In Completed Sheet".

    You can adjust what text appears "In these" when there's a count of 1 or more. Let me know if this makes sense or if you still need help!
