OsCommerce PayPal Integration

1. On the Seller Biller info page, I want the sellers to enter there Pay Pal information. (Not Credit Card Information) (This will be used when the buyer is checking out) 2. After the Seller is finished adding all of there items, they will have to click the "Pay Now" button in the invoice box, which will take them to PayPal to pay Its Minnesotan.com. (There items will not be posted to the site until the payment is complete) 3. When a buyer is checking out, they will pay seperate bills for items paid to seperate sellers at checkout. The sellers Paypal information given during seller signup should be used to route the payment. (Sample Code was attached and should help to guide you.) So my Paypal Information should only have to be attached to the Sellers Invoice Box.
