Usually, we're trying to identify the unique values in a list. This custom function does the reverse. It returns a unique list of duplicate values from a list (one value per duplicate).

This function have some issues, because when you try to past it into custom function, there are warnings about some variables that aren't identified. Developer, 1. How is possible to have "1" or empty "" as function parameter? 2. The function parameter is List_of_Values, but you use a variable called Original_List. Thanks,

Hi found the problem, the tittle is wrong should be: IdentifyDupes ( Original_List ; i ; Dupes )
