Quick php task - immediate need

I have a custom coded upsell function in php and mysql on my site. The upsell sequence path is stored in and called from a MySQL database. There are 3 offers total in the upsell sequence. The upsell function itself is working as far as taking the user through the process, but the 2nd upsell offer payment is not being processed through [login to view URL] Of the 3 total offers - the first initial offer transaction processes without issue, 2nd offer does not process payment, 3rd offer transaction processes without issue Although the payment is not processed for the 2nd offer, the student IS registered in that course and given access to the product. So the issue is strictly in the payment processing portion of the function for that page only. I have another upsell sequence that uses 3 other products, and that one procesess ALL payments without issue. I am looking for someone with excellent php knowledge who can work on this for me right now. I need it functioning asap! (the next couple of hours hopefully!!!) I look forward to your bids. Thank you for your time! :)
