I don't know how your form is set up. The way I normally build a parent-child form is by placing the parent control on the form and adding a read-only grid for the child. I would add 3 command button: Add, Modify and Delete. The first two buttons would display a modal form to add all the information about the child.

In the Save method of the child form, I would issue a INSERT-SQL to the child table if the Add button was selected in the parent table.

In the Save method of the parent form, I would put a TableUpdate() for the parent table and a second one for the child table. TableRevert() for the Cancel method.

Naturally, this require a record/table buffering for the parent table and table buffering for the child table.

>Thanks for your reply!:) I really needed someone to verify my fears...ok, I see what you are saying, can you give an example, or suggestion on how to do this?
