I'm not sure I follow you.

Let me try to simplify. You have a parent table, PARENT.DBF. You also have a child table, CHILD.DBF. The CHILD.DBF has a column called ID, which is its primary (surrogate) key. CHILD.DBF also has a column, FNAME, a "user friendly" description of the "unique thing" about this record. For this example, I'll use first names. The PARENT.DBF has its own ID column. ID is PARENT's Primary (surrogate) key. CHILD.DBF also has a column called PARENTID, which holds the surrogate/primary key from its related parent record.

Are you asking how to give your users a form which will allow them to view the values from the PARENT record along with the related FNAME's from CHILD.DBF?
