Can Anyone Help Me!!!!

[Mitz_Laddy]

BackGround: I have an quote and invoice system to develop, for each quote there are set jobs, from the :Quote table these are saved in :Quote_Details, when creating an invoice they want the ability to select certain jobs from ::Quote_Details - I have the selection working to copy the required fields into a table ::Invoice_Details. ::Invoice is related to ::Quote, and calls ::Invoice_Details via a portal.

Problem: When I create another invoice for a paticular quote, the portal brings up all the invoice details for the original quote. I need a blank portal for me to add other jobs, without showing the detials of jobs already invoice. Im really stumped on this and need to figure a way of linking ::Invoice to ::Invoice_details but I've chopped and changed it so many times with no result - can anyone help me??
