I have a Paypal module installed on my OsCommerce based website which we used to use. It is now turned off as we use SagePay (formerly known as Protx). I would like to turn it back on again but when I do that and try to place a test order I get referred to the Paypal site and get the following error message "The link you have used to enter the PayPal system contains an incorrectly formatted item amount." There is then a button to return to merchant.
I need someone to have a look and sort the problem please. I think it must be a really simple problem as it used to work. I am hoping that with this option enabled I will be able to accept Paypal payments, as well as credit cards via Paypal.
