I can't get the dopplr badge to work in my Sidebar. I'm using the HTML plugin, but it just displays blank space. There is some javascript - perhaps that's not allowed? Is there a workaround?

FYI -- the 30boxes badge that is javascript-based did not work either. I saw another post that perhaps the HTML was too "long" for the widget. However, the dopplr code is only about 3 lines.
