The client asked me whether I'd be able to give an itenerary of the products a client has ordered through the site so I removed the Paypal contribution from the oscommerce site and installed the IPN. It works fine with the aggregate method but when I changed it to Per Item it gave the following error Here is the data which is being sent from the checkout_confirmation.php page If you need the data which is being sent when an aggregate post is sent to Paypal to differentiate what the problem is with the per item method then I have the text available to paste onto the thread. Thanks in advance for any help.
I've just noticed the invoice field doesnt have any value assigned. Will this make a significant impact on what appears on the Paypal page?
