Hi Dennis,
If you have performed the steps previously outlined successfully, then you should have a parent table and a client table with a persistent relationship. The persistent relation estiblished between the parent table's primary key, that is related into the child table's foreign key, should persist even in a form that is governed by indexes other than the persistent relationship index.
You should be able to open the DBC exclusively, and right chick on the DBC's desktop. Then select "Edit Referential Integrity" from the menu that appears. A wizard should appear to guide you. If you mess up, just kept trying again until you learn how to use the wizard to achieve the desired referential integrity effect.
