Baffled by the Basics

[aftershokk]

I have one form and a table with an autonumber id field. I have a second table with an ID field as a subform. I set-up the master and child links.
When I add a new record to the main form the new id appears in the main and subform but the new id does not appear in the subform table???

I am confused?

The add new record works BUT
I created a copy record from the wizard but it only copies the main form to a new record. I want to copy and paste the data in the main form and the subform and still create the new id in the mian form and copy this id to the subform.
any ideas?
