I have a couple items for purchase that are rebilled either monthly or annually. I accept payments via Paypal. Do I use Paypal's Subscribe option, creating the subscription in Paypal itself and entering the Paypal Button Item Number when creating the product in AMember? If so, do I still choose the rebill option to match the settings I create in Paypal? I'm assuming these two need to match, right (Paypal settings and AMember settings)? There is nothing in the documentation that clarifies this.
