Document is null or not an object
I have an application that is giving me a Microsoft jScript runtime error of " 'document.xxx' is null or not an object ". The xxx being the name of a function. The tool image is supposed to change depending on what is put here. During the error message, if I select OK and not to debug the application then runs fine until I load it again in my browser. Can anyone find a solution in my code?
The application can be seen at http://munimaps.muni.org/website/sweeping/default.htm
Browsers that have error checking turned off will probably not see the error.
