I copied rows from an old sheet to a new sheet in bulk. After doing this, I began adding new rows to the new sheet via a new intake form for that sheet. the first new entry I put in gave me a project ID that was identical to an entry that I copied over from the old sheet. How do I prevent this, as I can't have duplicate project IDs and I can't change the old IDs?
To clarify more, this Project ID column is an auto-number column and it is NOT my primary column. So, maybe I'm just wondering how to get auto-number IDs that are not duplicate of existing ones?
