Uncaught TypeError jquery function is not read anymore
You got it - basically it means the function isn't defined or is conflicting. You have to load the jQuery file that you're going to use and not multiple or you'll get that type of strange behavior. 

The workaround I've used, which does work -- assuming you're not using that particular function -- is to define the function yourself as an empty function and it'll reference that and just keep on going. This came up in the Adobe Edge beta as fnCycle() was giving the same error. After putting the empty function in my own .tpl.php is solved and didn't kill the js execution.

Note though that while this may work for that one situation, you will have others if you leave conflicting versions of jQuery in there.
