I think you have an earlier error that is resulting in this one -- the console log is cut off in your snapshot so I can't see all the previous errors.
I also see in the console log that the "harnessResize" function is undefined, and that also is incorrect.
Since things work in Chrome, I'm wondering if you have a race condition in IE, and the required JS has not yet been downloaded by the time it is needed.
You might debug in Chrome (you can add a "debugger;" statement in the onclick event prior to the "pd(event)" so that you can then step into "pd" and see where it is defined. Then determine why it is not getting loaded in IE -- either a race condition, or some other JS error is blowing it up.
