When I try to re-index the database, and the program says I have duplicate codes. What does this mean, and how can I fix them?

 In

Duplicate codes occur when 2 or more entries in the database contain the same CODE field. This situation can occur if indexing is no longer accurate, or if you have Movie code/Customer Code indexing set to off. Both scenarios cause the program to be unable to check if a code exists, thus the same code can be assigned multiple times.

Duplicate codes can be fixed by pulling up the movie/customer by its Record # (either Movie # or Customer #) and changing the ‘code’ field to a code that has not been assigned.
