[jQuery] Clear Formatting Jquery Corners

I will start by saying that I am a complete newb when it comes to
jquery. I am trying to use the jquery corners http://www.malsup.com/jquery/corner/
product to create rounded corners in a drupal 6 theme. I have the
corners rounded, but the issue that I am running into is that the
corners style are being inherited all the way through the menu instead
of staying on the top level. I have included my code below. Any help
would be appriciated. Thank you in advance.
