OScommerce fix

We need someone who is clever with php, oscommerce & MySQL databases. The problems are 1 : On our PHP powered webshop (OScommerce) we are unable to admin the site properly. When we try to add new products, or edit existing ones, it all seems to enter ok, untill I hit the update button, when the new information is not recorded and all the products information fields (price description sizes etc) end up blank. It all worked fine on our previous shared-hosting solution with Lunarpages, our present webhosts, but when we changed to the new VPS solution the problem arose, and we cannot work out why ! 2 The next problem is with our webshops MySQL customer database. Briefly, the problem is to do with the customer-default-address-id, which should be unique, but due to a bodged database merge, now has 930 customers who share a 'unique' number with 930 others ! How do we give these 930 customers new ids and enter their addresses into the database , and ensure that all new customers will get a unique id from now on ! ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
