I need Help on a JQuery navigation

[eluser]Référencement Google[/eluser]
Hi all,

Not CI related but I post my request on my favorite forum...

I am trying to implement this SuckerFish navigation on a website:
http://be.twixt.us/jquery/suckerFish.php

My problem is that it's working with a old version of JQuery but with a new 1.2.3 it seems that some elements of this code has been depreciated by the library. I am not good enough to find which one, so I need help of the JS specialists!
