Css Drop Down Menu

Hi experts,

I'm trying to use a css drop down menu into my website.

Here are the source : Css3 Drop Down Menu .

Here are my troubles :
- the 4th last menu, start at "products", marked with the class "menu_right" ; must be aligned at the left of the container (<ul>) but it don't work.
- the top menus marked with class "drop" don't work too : normally a small picture (an arrow - drop.png) must be showed at the right of the menu, to indicate that a submenu exists.

How it should be :
menu-prototype.tiff

How it is now:
 menu-now.tiff

Do you have an idea what's wrong ?

I have applied all the css & html code as follow :
- css : the same code as the final example except the width of the menu

#menu
{
	/*width: 940px;*/
	width: 90%;
}

- html :

<ul id="menu">
	<li> <!--- index group (Home) --->
		<cfinvoke returnvariable="variables.indexPages"		component="tools.pagesTools" method="getPages" group="index">
		<cfloop array="#variables.indexPages#" index="variables.page">
			<cfif variables.page.getPosition() NEQ 0>
				<cfset variables.pageName = uCase(variables.page.getTitle())>
				<cfoutput> <a class="navigationBarLink" href="#variables.page.getUrl()#" onclick="processing();">#variables.pageName#</a> </cfoutput>
			</cfif>

</ul>

I attach the both concerned files ("2_navigationBar.cfm" -> renamed in "2_navigationBar.cfm.txt" & "navigationBar.css")
I also attache a print screen of the look of my menu now (menu_now.tiff) & a prototype of how it should be (menu_prototype.tiff).

Well, the code is in html & coldfusion, but no matter, it works fine, just the css who does tricks to me :-)
The coldfusion code just retrieve the different page names.

Thanks a lot.
