Linking Post Affiliate Pro With Membership

Hi,

We are trying to link an affiliate program with the payment gateways for membership.

There are a couple different methods that can be used depending on the HTML code for the payment button. Since it has a "Notify URL" this post suggests we should be using this method

We are finding this terribly confusing, and we were hoping one of you brighter helpful people could maybe give us some advice.

Is it just this section of the button code we have to edit and if so could you please show us how it should be.

name="notify_url" value="http://www.5starsignals.com/paymentreturn/paypalexpress"><input type="hidden" name="no_note" value="1" /><input type="hidden" name="no_shipping"

Your help would be greatly appreciated.
