James - Can you please give us a little better example of what you are trying to accomplish?  The question is a bit vague.

What information? What previous form? Like Scott said, we need more info.

Yes question is vague.  If I had to guess.  Maybe have a form where client information is entered on main form, then on another form in the header section have the client information (Name, order number, etc) and in the detail section a subform that can be opened as a new record.

Question is that, if I would want to create an "New Invoice" for the current Client. How can I open up the "Add New invoice Form form the "Client Account Dashboard Form" and have the Client's Info automatic popular the Form's Fields?
