Need help with Paypal Sandbox

[Icarus]

Hello everybody,

I hope this is the right place for such a question.
I am having problems configuring PrestaShop to properly work with the Paypal Sandbox.

This is what I have done (and following are the results).
1. In paypal sandbox, open two preconfigured accounts - buyer, and seller (business)
2. In PrestaShop configured the Paypal module to use my sandbox seller email, sandbox radio on
3. I then register to my shop as a user, and make a purchase
4. I am then redirected as expected to paypal, making a successful payment
5. Pressing the button to return back to my shop

The results:
1. I am redirected back to the History page
2. This page contains a message "You have no orders"
3. After a few minutes, I receive an email (as the buyer) saying there was an error with my payment
4. In Presta, in the order history page, I now see this error order
5. In Presta (as admin) I also see this error, and it says it got a payment or $0 instead of $20

Can someone help?

Thanks in advance.

EDIT:
The "No History" problem seem to be solved by itself.
The only problem left, is ths $0 payment received.

You will get that 0 error if you are trying to login to your business paypal account for paying instead of a personal sandbox account like being a customer.
