Can't get there from here...

I know I'm doing something wrong; but what is it?
I got the editing done (Garage Band, Audacity, Itunes),
I got the clip converertedinto an Mp3(Switch),
I got the clip uploaded to Hipcast (tried Odeo, too),
I got it published to our class blog for this purpose(Hipcast),
I even got to the source code and copied it.
But Blogspot will not let me post it into the source code on my blog.

It looks like this:

Well, I can't show you the code because the editor tells me there's something
wrong with it. Sigh. Big sigh..

Just can't get there from here.
