I'd suggest you take a look at the "scmerlin_www.asp" file.
The key change to fix that specific error was to have the following 3 JS files in this order:
Rich (BB code):... src="/js/jquery.js" ... src="/js/httpApi.js" ... ... src="/client_function.js"

HTH.
Playing with it a little further it seems something else was depending on client_function.js, moving it to the third position overall resolved the issue.
