CSS + jQuery scrollable navigation

Hey all,
Im new here, sooo, Hi :wink: I found out of this great resource from Smashing Mag & it looks exactly what Im after.
Im just trying to put som extra bells and whistles on a site im working on and hit a bit of a snag.

Hopefully this isnt too much of a problem, but Iā€™m struggling to fix it.
I want to use this jquery navigation on a site im working on: http://flowplayer.org/tools/demos/scrollable/site-navigation.html

and while I can get it work on a basic page, when I start to put it within divs ive already styled, it stops working. you can see examples here:

working:

not working:
http://www.georgianwines.ie/grape_var_test.php

so im pretty certain its my existing CSS stopping the animation from executing, but im a bit stumped. any ideas guys? much appreciated!
cheers

ok, well after some further invesitgation i found the culprit. a tiny bit of script that is allowing me to do the dropdown menu.
when i remove it from the page, it works. :-/
so my problem is no longer a CSS issue, so apologies if im in the wrong forum !!!
this is the offending bit anyway:


<script type="text/javascript"> 

ddsmoothmenu.init({
	mainmenuid: "smoothmenu1", //menu DIV id
	orientation: 'h', //Horizontal or vertical menu: Set to "h" or "v"
	classname: 'ddsmoothmenu', //class added to menu's outer DIV
	//customtheme: ["#1c5a80", "#18374a"],
	contentsource: "markup" //"markup" or ["container_id", "path_to_menu_file"]
})

ddsmoothmenu.init({
	mainmenuid: "smoothmenu2", //Menu DIV id
	orientation: 'v', //Horizontal or vertical menu: Set to "h" or "v"
	classname: 'ddsmoothmenu-v', //class added to menu's outer DIV
	//customtheme: ["#804000", "#482400"],
	contentsource: "markup" //"markup" or ["container_id", "path_to_menu_file"]
})

</script>

But this basically allows the dropdownmenu to function or not, so removing it isnt the best of options.
As im not really a coder, so im pretty stumped to say the least. Can anyone offer any help on this. Id be much appreciated.
Thanks Alot.
