CSS Drop down not working in IE6

I have a drop down menu on a website that I’m working on at:
http://www.themortgagesalesblog.com/home/

The drop down effect doesn’t seem to be working on IE6, but it does work on IE7.

Here’s what my CSS looks like:

/* Root = Horizontal, Secondary = Vertical */
#navmenu-h { background: #000; }
#navmenu-h li.alignright { float: right; }

ul#navmenu-h
{
	margin: 0 0 1em 0;
	border: 0 none;
	padding: 0;
	width: 950px;
	/*For KHTML*/
	list-style: none;
	height: 36px;
	border-bottom: 1px solid #fc6300;
}

ul#navmenu-h li
{
	margin: 0;
	border: 0 none;
	padding: 0;
	float: left;
	/*For Gecko*/
	display: inline;
	list-style: none;
	position: relative;
	height: 36px;
}

ul#navmenu-h ul
{
	margin: 0;
	border: 0 none;
	padding: 0;
	width: 160px;
	list-style: none;
	display: none;
	position: absolute;
	top: 36px;
	left: 0;
	border-left: 1px solid #fc6300;
	border-right: 1px solid #fc6300;
	border-bottom: 2px solid #fc6300;
}

ul#navmenu-h ul:after /*From IE 7 lack of compliance*/
{
	clear: both;
	display: block;
	font: 1px/0px serif;
	content: ".";
	height: 0;
	visibility: hidden;
}

ul#navmenu-h ul li
{
	width: 160px;
	float: left;
	/*For IE 7 lack of compliance*/
	display: block !important;
	/*For IE*/
}

/* Root Menu */
ul#navmenu-h a
{
	padding: 0px 20px 0 20px;

	display: block;

	text-decoration: none;
	/*For IE*/
}
