OsCommerce site using PostFinance Payment Module and PayPal Module.
Problem: Orders are being confirmed when payment is abandonned, aborted, or unsuccessful. Need to prevent confirmation of orders unless payment is successful. Customer needs to get an unsuccessful order page if payment is not successfully completed.
Problem 2: Need to create a conditional situation where a certain shipping method is available only for orders above a certain specified amount.
