ASP.NET Website Session Errors

I have a website that has been created in Visual Studio 2008 professional edition. The website works 100% whilst testing using the debugger (F5) using localhost (on my laptop) but when I move the files to the Business Server 2003 initpub folder (another computer), session variables seem to be lost and the website crashes. The error occurs whilst going through a asp:wizard control. I keep getting 'Object reference not set to an instance of an object'. (A session variable is null but it HAS been assigned!). It seems to be getting lost! I need a professional to take control of my screen using msn and sort the problem. ## 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.
