Emergency Debug / Fix

I have an ASP Program that uses SQL Server data and Frames to get the screens to form the way we want them and alot of JavaScript to complete calculations - etc. This has been in place for several months with almost no problems and all of a sudden yesterday it started intermittently getting to a particular point and won't complete the script calcs and therefore won't work to add items to the quote. - If you refresh it takes you back to originating screen where you can go back and edit the quote which then you can start adding items again fine and then all of a sudden after a few are entered it will lock up again. I thought it was a slow data server but the host swears the server is fine and the data does load so somhow the script is being blocked but I can't figure this out. The guy that wrote the script is no longer with us so I just need someone to review the section where this happens and find what is going wrong - and fix it! I will give ftp access to the winner so you can test on site. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
