Regarding Paypal

Hi nopCommerce Team and nopCommunity,

I have setup Paypal Direct, Paypal Express and my return URL to PaypalExpressReturn.aspx. Also my Paypal's Sandbox API username, password and signature are setup.

Have tested it and went flawless, as in no errors logged and no errors displayed on my way checking out. But when I've checked my sandbox business account balance, I'd receive nothing. I am confused. Any ideas?
I am using version 1.4.

Your suggestions are much appreciated.

This problem was solved with more caffeine in my blood.

Just to clarify...

What is the Auto Return - Return URL?
What is the IPN handler - Notification URL?

Are these 2 for the Auto Return - Return URL?
PayPal Standard: http://www.yourStore.com/PaypalPDTHandler.aspx
PayPal Express: http://www.yourStore.com/PaypalExpressReturn.aspx

If so... what is the IPN handler - Notification URL?

Notification URL: http://www.yourStore.com/PaypalIPNHandler.aspx
