She wants to add a code to the database that assigns a 1 to the item if it is unique, and if there are duplicates, assigns the number of the duplicate. An example is shown below. The first two items are unique, so the repeat code is 1 . However, Item iD 37700 is listed six times, so the codes are assigned from 1 to 6 , and so on.
