'Duplicated entry for PRIMARY key' (no replies)

Hi

I have constantly been getting a duplication error.

When I queried the id in the slave db, no results return but they exist in the master db. If I try to skip this error, I then receive a foreign key error.

Please could you tell me how to fix this problem.

binlog format: statement
master mysql version: 5.1.58
slave mysql version: 5.1.73

Thanks
