UI TABS problem

UI TABS problem


Hi everyone,
I am new in jquery and i have looked over all tutorials over the net,
i still have problem with the ui tabs. the panels are not disappearing
when i declare the ($("div > ul").tabs();.
I have posted my code at http://dpaste.com/35440/
If anyone can tell me where is the problem. i tried everything. i
start to wonder is i have to use a specific CSS file and not the won i
created, like Flora that comes with all the examples in the net.
please help
Thanks,
