Embed Google Form in Joomla 1.6

[[email protected]]

I am trying to embed a google form into a joomla 1.6 article. Is there a walkthrough for this? I am trying to follow the example here:

but I am not able to get a form to work. I have installed Jumi, but all I see in the page with my form is "loading."
