Visited links black in Firefox and IE

Can’t figure out why visited links in the top nav turn black in firefox and IE.

See:

Thanks for any help!

#nav {
	height: 31px;
}
#nav ul {
	margin: 0;
	padding: 0;
	float:left;
	list-style: url(none) none;
	width: 628px;
}
#nav li {
	display:inline;
	float:left;
}
#nav li a:link, #nav li a:visited {
	display:block;

	text-decoration: none;
	background-image: url(../images/navbutton_bg.png);
	background-repeat: no-repeat;

	text-align: center;
	padding-top: 9px;
}
#nav li a:hover, #nav li a:active {

Hi,
It happened because it is being overridden in the cascade.
On line 107 in your css you have this -


#subnav_right a:link, [B]#nav li a:visited[/B] {
    [B]color: #000;[/B]
    text-decoration: none;
    
}

Oops! Thanks Rayzur!
