[TYPO3] Paypal not returning values to Webformat shop

[shielsn]

Hi,

Has anyone had any problems setting up the Paypal gateway for the Webformat 
shope extension?

The shop sucessfully sends the visitor to PayPal to process the payment.  We 
have configured the return page to be the basket page.  However, once the 
payment transaction is complete the visitor is returned back to the basket 
page, but not to the finalize order page.  As well, no order is recorded in 
the backend.

We have also set up Paypal to return to the basket URL as well as setting up 
IPN.  Still not working.

Perhaps we need to add some sort of parameters to the return URL?  But what?
Any suggestions would be greatly appreciated.
