Quick fix for PayPal module on oscommerce site

We require a freelancer to fix some code on a website. When someone places an order, the details do not appear in the admin panel orders section and the variables are not passed to PayPal when the customer checks out. I am unable to upload a document that contains information from PayPal as it appears it contains coding and this site wont allow it. If you visit the following link, there is an explanation there: [login to view URL] NOTE: There is NO facility in our admin panel to turn on itemized option so we are at a loss as to why the details are not being passed. We will not make any payments until we are satisified the coding is working correctly and to our specification. Previous freelancers who have let us down before, need not bid. We will award this straight away to the appropriate bidder as this job is required urgently. If you need any further information, please PM me. Thank you
