COLDFUSION eCommerce UPS module problem

The website has been operational for sometime and generates traffic and sales.? It started out with a simple ColdFusion eCommerce Application which has been heavily modified. There have always been some small bugs which get worked out, but there are experiencing errors which I believe are related to UPS API code. I need the UPS integrated code fixed operational.? The person that integrated this did a wonderful job and they are busy so I need someone fast, like yesterday. ## Deliverables This eCommerce site is live and was operational up until this weekend. The website / eComm store code is experiencing some errors which are generated during the SHIPPING METHOD option during checkout. The UPS code needs to be fixed. I can provide the code and files that are in question and a URL.
