Bug on .ASP that uses JScript

I have a .asp site that is a kids coloring book. Some times when I people go to the coloring page (the page where you color in the image) - instead of showing the image to color in you see this strip of code: Microsoft JScript runtime error '800a01fb' An exception occurred /[login to view URL], line 18 I need for this error to go away. The solution could be as simple as fixing the code on line 18 or it could be as complicated as having to rewrite the code to make the site stable. Not sure. Attached is the page with the code that is causing the bug (the code is on line 18). My main concern is that multiple user sessions seems (6-7 user sessions) to cause the site to crash and provide this code. So there may be work required to make the site handle a large load as I would like to be able to handle several hundred simulatanious sessions (obvioulsly we would upgrade server config) but the code has to be stable. Additional Description: The following was added to the description on Mon Dec 10 09:40:06 2007, after the project was originally posted. I will pay 25% upfront. The remaining 75% will be paid only upon successful stress testing on the site where we have simultaneous users using the site. As stated earlier - the objective is for this code to be scalable. It may require that other pages on the site be updated. ## 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.
