[jQuery] Plugin development "handler is undefined" ?

[jQuery] Plugin development "handler is undefined" ?


Hello,
I'm trying to build a re-usable plugin for a current project and I'm
getting strange errors in the Firebug console. At one point I was
seeing "G is undefined", which didn't effect the function of the
plugin itself, but it was there nonetheless. Now when I have two
instances of this method running on one page the second seems to break
and I'm thrown a "handler is undefined" error in the Firebug console.
Here's a minimal test case:

Any help on this is much appreciated, I'm stumped.
Thanks
