How to Flag Possible Duplicates for Review?


I’m trying to find a way to flag potential dupes in my base, and I’m no expert so I need a little help.

All I really need to do is see anything where the combined first name and last name fields I have match. From there I need to manually review. But at this point I can’t even determine how to best find the first/last name dupes without scrolling through what is approaching 1000 lines.

Anyone willing to give me a little insight into how I might flag entries that share those two fields?
