Thanks, I adjusted and this was the reason:

"Cannot insert the value NULL into column 'numero', table 'Direct Martial Arts.dbo.erreur'; column does not allow nulls. INSERT fails. The statement has been terminated."

When I imported the data from VFP, the import module didn't consider the auto incremental fields. So, I would have to adjust that manually.
