Error in duplicate record in Access 2010

I should work with a database into the Access 2010 recently. It has few Tables, a few Queries based on their tables and finally a Form. The Form has a button for duplication records. When I click the button then I get this error message: “some of the field names you tried to paste don’t match field names on the form” … after passing of this message, some of fields have been duplicated (only a few fields) and most of all records have not been duplicated and they are invisible in the Form. I changed the fields name into the related table but the issue still remained.
Do you have any idea for solving this issue?
Thanks
