299866 Affiliate script - basic help

Ive just bought Webaffiliate to go with my Webdate script and am having problems with 1 stage of the setup. The webdate "support" team has clocked off for the weekend without replying to my cries of help so I'm turning to you lot . I'm willing to pay someone to tell me how to do this: Getting Your Sales Recorded In order to have the webAffiliateâ„¢ system properly credit a commission and sale, you will need to route a customer who has successfully completed a sale through http://YOUR-BASE-WEBAFFILIATE-URL/[login to view URL], where YOUR-BASE-WEBAFFILIATE-URL is the URL to the directory that houses the main webAffiliateâ„¢ script, and X is the ID of the product sold (you can obtain the product ID for each product by viewing the Products screen in the administrative backend). You can route the customer through this script in a couple of ways: By using this script as the return page for your payment gateway. After processing the sale, it will return the user to the URL that you have associated with the product. By including it discreetly on the return page as a one-pixel image: In this case, no image will be seen, and only the processing occurs "in the background." In either case, remember that you have to change the ID sent to [login to view URL] appropriately for each product. Otherwise, your sales and commissions will not work!
