CSS LIST NAV not working on IE 6

[tuba74]

So I finally got my list navs to work then I looked at it on IE 6 pc- FAILED!
Am I missing some tag or do I need to hack it and call out a special style for IE 6? This is my first list nav attempt and I need help. thank you in advance.

Try

#pipe li a {
	/*background-image:url(images/navline.gif);*/
	background-color:#999;
	color:#333333;
	padding:0 19px;
	margin-right: 0px;
	text-decoration: none;
	height:52px;
	line-height:52px;
	float:left;
}

#pipe li a:link {
	/*background-image:url(images/navline.gif);*/
	background-color:#999;
	color:#333333;
	
	margin-right: 0px;
	text-decoration: none;
}

#pipe li a:visited {
	/*background-image:url(images/navline.gif);*/
	background-color:#999;
	color:#333333;

	margin: 0px;
	text-decoration: none;
}
#pipe li a:hover {
	color:#ffffff;
	background-image:url(images/navline_on.gif);
	
	margin: 0px;
	text-decoration: none;
}

#pipe li a:active {
	/*background-image:url(images/navline.gif);*/
	background-color:#999;
	color:#333333;

	margin: 0px;
	text-decoration: none;
}

PS: The pseudo classes should be in the order link,visited,hover,active (LoVe-HAte), otherwise it may cause some unexpected issues in IE.
