Can anyone help me figure why my menu does this in IE?

So i created this website: http://www.ritztheatre.net/ but im having troubles with the menu in IE-7 and 6.

In IE-8, Firefox, and Chrome it looks normal heres a screenshot of it in IE-8:


In IE-7 the submenu rollover shifts to the side..



In IE-6 the submenu covers the top nav when rolled over..


Heres my HTML code im using for the navigation:

<ul id="nav">
<li><a href="#" title="Get Tickets">Get Tickets</a>
         <ul class="sub">
         <li><a href="comingsoon.html" title="Vip Seating">VIP Seating</a></li>

thank you for taking a look

 

hmm. try adding "px" to your integer values...

also, maybe add

ul{
margin:0px;
padding:0px;
}

so it applies to all UL's

I think it's your ul's default margin and padding that is causing the shift.
