To complete this payment, add a debit or credit card to your PayPal account

Hi. So when i test the purchase i get taken to the paypal sandbox site where it asks me to login. I enter my sandbox email and password and i get the message...

"To complete this payment, add a debit or credit card to your PayPal account" etc.

So how do i get past this? Is this something that i need to change in my paypal account or is it something i need to change in the Joomshopping backend?

You advice would be greatly appreciated.

Thanks.

Just a guess, but do you need to use the option to add 'virtual' money to your sandbox account so it can cover the payment without a backup funding source?
