Sub menus (yes again… but i need help)

I menu-ized my theme by adding the code to my functions php file.

I then added this to my header to display my menu..

<div id="nav">

<ul>
	<?php wp_nav_menu( array( 'container_class' => 'menu-header' ) ); ?>

</ul>
 </div>

When I try to do submenus it just plpps the submenu under the parent menu item. It doesn’t allow you to hover and have it appear, it just plonks itself in and screws up the menu.

Any help would be greatly appreciated!!!!!!!!!!!!!!!

Please!!!!!!!!!!!

I have it with a submenu so you can see what it is like. The sub menu called ‘test junjk’ is suppose to be under ‘Meetings’.
