Additionally, the above code works as well, which is simplier and doesn't rely on the ui-accordion-link class being present.  Which was posted prior.  If it does not, please let me know, and I'll send you back a link to a zip where you can download my test project that I was using.  It's possible that you are using a different or older version of jquery and/or jqueryUI that this does not work in, and I would recommend you upgrade.  I used jquery 1.7.1 and jquery ui 1.8.16.
