How to embed Javascript on TWEN pages?

We recently subscribed to OCLC's QuestionPoint, and the service comes with a Qwidget feature (a chat widget) they we wanted to place on web pages & all the course TWEN pages in Westlaw.

Qwidget requires JavaScript, and at first glance, TWEN would not allow it, it just stripped it away.

But then I tried an IFRAME pointing to a page that just had the Qwidget, and TWEN was fine with it:

<iframe scrolling="auto" height="300" frameborder="0" width="200" src="http://lib.law.cua.edu/home/pages/qwidget1.html">

Make the frame a bit larger, so no scroll bars on horizonal or vertical.

Code box is from Tutzone 
TWEN is course management system from Westlaw
