My custom jQuery accordion script breaks in Internet Explorer

Forgive my amateur coding, but I've smashed together a crude p开发者_运维知识库age that uses jQuery accordion and loads the content of each drawer from a php file:

This works fine in Chrome and Firefox, but I get a javascript error in Internet Explorer and the whole thing fails.

For the life of me I can't figure out what's wrong with it... Any tips would be much appreciated!

lol, I think you can get rid of this:

<script src="scripts/jquery-latest.js" type="text/javascript"></script>

jQuery 1.1.2 is not quite the latest version.
