Oscommerce attributes problem in checkout

After upgrading to CRE Loaded 6.3 from an older version of OSCommerce the product attributes stopped working. No attributes are shown in the basket or in the order when it has been processed and sent to the admin side. I have tried to delete and re-enter the attributes but it doesn't work- When the upgrade was done the list of products which had attributes before were still listed in the product attributes section on the admin side but they had no Option Names or Option Types so I had to re-input these - I have looked in the SQL side and the data is there so I think it is a simple PHP code issue in the [login to view URL] or [login to view URL] files. The attributes are showing to the end users and are selectable so its just a case of the attribute data not being processed with the order.
