I have a contract table linked to a customer table and the autonumber field
has started inserting duplicate numbers and I can't figure why.

If a customer has multiple contracts and the tables are joined on the
customer ID (Autonumber) field then you will get duplicate customer Id's in
the contracts table.

That is as it should be.

I have experienced this when a table became corrupt. I had to delete any
duplicate IDs after repairing the table.

If you copy an Autonumber value into the Autonumber
field, it will reset the Autonumber field.

This can happen if you use an Append Query or an
Update Query that adds records. You can use another
Append Query to reset the Autonumber field again.
