Combo Box And Invoices

I have a table called vendors in that table is Company Name,
address, city, state and zip. I also created a form called vendors same information. On the form i have a combo box called bill to party which selects the name that will print on the invoice.

Ex Company Name ABC
Address What Ever
City State Zip
Phone

Billed to party (here is the combo box on the form)

However when i select the bill to party on the form from the combo box it is only showing the name of the billed party on the invoice and not the address city and state.

I dont want to create extra text boxes on the form so when i chose the bill to name on the form will fill in the text boxes I dont want to do this. All i want is to select the bill to party from the drop down menu and when i view the invoice it will automatically show up on the invoice.
