I cannot get the foreign key reference in a Parent/child form

[Roy]

I have a parent/child form that I have created without using classes in VB. When I want to add a new record, I click on ADD. I have a DAOcontrol.Recordset.addnew function for both the parent and child form. When I create a new record, I do not get a foreign key reference in the child form. The parent primary key is an autonumber from MS Access. This is the foreign key in the child form but doesn't appear. So when I call up the parent that particular child is missing. Can anyone help me
