combo box for sub report

[combine21]

I have a report where I am trying to create a packing list for products. rpt_product_inventory_packinglist. These specific products are clicked on in another query in which the report will go grab them based upon the buyer. In my report I also have a subreport rpt_Mailing_List subreport, which has the mailing information of the buyer. In the query that has my products, there is a field which has the buyers name in the record as well. I have created a form with a combo box in which I want to select a buyer and the report will pop up with the specific products only relating to that buyer and their mailing information will appear in the subreport. Currently when I click on a buyer, the report will show their specific products and every mailing address I have recorded. How do I tie the combo box selection to the report and subreport? Help please.
