I have a website that I recently moved the hosting to GoDaddy from IX Web Hosting. While it was on IX Web Hosting I had a payment site where people would go and enter a description and a dollar amount and hit proceed which would take them to the actual payment page. Well the first part works but when taken to the payment site the dollar amount is not shown in "Total Amount Due". Can can see the example here: [login to view URL] I also have another site that had a fixed dollar amount that would take them to the same payment page with the same results. That can be seen here: [login to view URL] and second one here [login to view URL] I need to get these working properly ASAP. It just a matter of fixing some code rather than creating it from scratch. Please list your prices and I will respond ASAP. I will provide you with all the files and info you need. Thank you, John Vizaniaris
