It's not a JavaScript error. I think this is being parsed when you don't want it to be. You want the following, or something similar, to appear on the page?
<?import namespace="DD_roundies" implementation="#default#VML" ?>
Well, the server thinks (I imagine), that you have PHP or some other server-side language embedded there, and is trying to parse that. So you'll have to change your server settings so that all files aren't being parsed.
There's probably another solution to deal with this specific file, but without knowing the precise details of your set-up, I don't know enough to say what it is.
