I'm using Yahoo Merchant Solution for my shopping cart. When a user is directed to the paypal payment page, the SHIPPING address the user has entered on my site is automatically copied to the paypal BILLING address... how can i make it so that the users' billing address is copied to paypal correctly? There are a lot of topics about this, but unfortunatley, with Yahoo Merchant Solutio, I can't look into its code. Thanks!
