WordPress MU

Hi there! I'm trying to insert a script on a page in my site that looks like this:

<script src="https://www-sgw-opensocial.googleusercontent.com/gadgets/ifr?url=https%3A%2F%2Fstoregadgetwizard.appspot.com%2Fservlets%2FgadgetServlet%3Fsandbox%3Dfalse%26mid%3D674049592137442%26key%3D0ArEtgUW7PxqtdEpxSS1fTXNSbWctRXl6dGFTNlV2SHc%26signature%3DdJMLBwp8UhxNcQY9qaYTT5ZVTLA%253D%26currency%3DUSD%26gadget%3Dlarge-store.xml&container=storegadgetwizard&w=600&h=200&title=&brand=none&output=js"></script>

Is there a plugin that I need to install to be able to do that, or is there a way I need to change the formatting of the code?

Thanks!

Yep, mu will strip it.

You're the only/primary user on your site, right? Then use the unfiltered html plugin.

Yup. What are the side effects?

Never mind. I read. :)
Thanks for this!!

The biggest issue to keep in mind with unfiltered-mu is that even as site-admin, if you switch to the visual editor on that post/page it will strip out the code again.
