ubercart paypal

Howdy,

Hope someone can help me out with what should be a simple task: Using Ubercart with PayPal Website Payments Standard. When the user completes the order, they should go to an order confirmation page and receive a confirmation e-mail. However, neither is happening. I believe the issue lies with using the correct 'Return URL' in my PayPal Website Payment Preferences.

I've tried http://www.example.com/cart/checkout/complete (with my own domain name of course), with no success. Any suggestions?

Thank you!

Is it possible to turn PayPal on and off based on the product?

For example, I am using Ubercart for event registrations. The events are set up as products and there are some events where we don't want to make online payment available. Yet, there are others we would like to have PayPal included.

Is this possible with PayPal and Ubercart?

I'm so frustrated with trying to get information from PayPal and FNB. Can anyone please answer a few questions for me regarding PayPal as a payment means on a South African eCommerce site, geared toward servicing a South African market?
