[Solved] Weird Nav, image not repeating...

I have an image for the background of my nav, and I can't get the image to repeat when the user increases the text size in a brower like firefox. I am using the same image for the footer navigation and it is working perfectly. The big difference that I have between the two, is 1) the top nav has a drop down menu, and the bottom doesn't and 2) the top nav has a height set to it... which is probably causing the problem, I realize, but without it, I you see the color of the navigation and that's it, the image stays tiny and still doesn't repeat. Here is the code for the css
/*-- Nav --*/
#nav{
width: 800px;
height: 30px;
background: url('../images/nav.jpg') repeat-y center;
font-size: 14px;
padding: 0;
margin: 0;
list-style: none;
line-height: 1;
}

#nav ul{
padding-bottom: 3px;
padding-left: 20px;
padding-top: 5px;
text-align: center;
text-decoration: none;
margin: 0px;
}

#nav li{
display: inline;
text-decoration: none;
padding-right: 10px;
}

#nav a:link {
color:#FFFFFF;
text-decoration: none;
}

#nav a:visited {
color:#FFFFFF;
text-decoration: none;
}

#nav a:hover {
color:#999966;
text-decoration: none;
}

#nav a:active {
color:#FFFFFF;
text-decoration: none;
}

#nav { /* all lists */
padding: 0;
margin: 0;
list-style: none;
}

#nav a {
background: #CCCC99;
display: block;
}

#nav li { /* all list items */
float: left;
width: 6em; /* width needed or else Opera goes nuts */
}

#nav li ul { /* second-level lists */
position: absolute;
background: #CCCC99;
width: 6em;
padding-left: 0px;
text-align: center;
left: -999em; /* using left instead of display to hide menus because display: none isn't read by screen readers */
}
#nav li ul a:hover {
background: #FFFFFF;
}
#nav li:hover ul, #nav li.sfhover ul { /* lists nested under hovered list items */
left: auto;
}
The site is http://www.spiritex.net The nav is also having an issue where it's not centering...(to see this in action, you'll have to look at http://www.spiritex.net/test ) If anyone has any ideas, I'd greatly appreciate it.
