Thanks for your response. I have taken a look at the library management application but I cannot see where the PayPal integration is done. When I click on the "Pay By Credi Card" button i get the following prompt: "Credit card payments can only be made after a valid PayPal account name is specified in System Settings. This can be done by library administrator."
Once I log in as the admin for the library system I can't see where the paypal account name is specified.
Is there any documentation I could possibly take a look at which may explain a little bit more about this?
