Forms :: Open New Form From Selected Group Of Records

I'm developing a database where people basically can fill in an order form and then the database can track if the order has been placed, when it came in etc.I have a form called frm_Suppliers to be Ordered that runs off a query. The tables that relate to the query are called tbl_Products, with a primary key called ID and tbl_Suppliers, with a primary key called Supplier ID.

The form called frm_Suppliers to be Ordered, shows a list of suppliers that have open orders. Each supplier may have several orders open. I want to be able to click a button after each supplier name and bring up a continuous form that relates to all the records from that supplier that have open orders.

I have tried using the code found in the thread called "open a form based on the record that is selected in current form" from 06-08-2011, however it will only work when my form lists each open order separately, not when they are grouped by supplier.
