Emergency code fix PHP update glitch

Need a quick fix. My ISP updated to the latest PHP and it now stops on this line: Line: 77 $orders=$db->db_result_to_array($query); Which is in a routine that lets us pick up boat decal orders entered by customers into our system. I need a quick easy price for fixing this line of code. ALl the rest seems to be working ok. Please price this under the assumption it will be only this line of code and possibly 2 or 3 more bumps that may show their ugly face once this line is corrected. If it is bigger than this, you are not required to do the job. I will pay more or we'll abandon and I'll advertise again. While in this code to fix this, you can price for me some additional features I'll want in an upgrade to this system. You can see this at [login to view URL] This is the design code. the probem is in the administration code and it stops us from entering the order database. Please rush your best quote. I'm awarding this quickly.
