I've been trying to get this code working but I'm getting an error stating: Cannot find a script or an extension object associated with namespace 'http://www.umbraco.org/randomTools'. Any idea if this was moved or is it broke? Should I be using something else? Maybe it's included in the library somewhere now? Any help would be greatly appreciated! Thanks!

This is what I get when running a debug:

Cannot find a script or an extension object associated with namespace 'http://www.umbraco.org/randomTools'.
