This is my layout http://anime.vibrantstream.com/wordpress/
The multiple column list isn't working if the text is too long which causes the next li to skip and go to the next column. How can I fix this?

Code:
body {
	margin: 0px;
	background-color: #000000;
	background-image: url(images/bg.jpg);
	background-repeat: repeat-x;
	background-attachment: fixed;
	font-family: Arial, Helvetica, sans-serif;
}

#wrapper {
	width: 970px;
	margin-right: auto;
	margin-left: auto;
	border-right-width: 1px;
	border-bottom-width: 1px;
	border-left-width: 1px;
	border-right-style: solid;
	border-bottom-style: solid;
	border-left-style: solid;
	border-right-color: #4394ab;
	border-bottom-color: #4394ab;
	border-left-color: #4394ab;
	overflow: hidden;
	background-color: #272727;
}

#header {
	background-image: url(images/header.jpg);
	height: 200px;
	width: 970px;
}

	line-height: 29px;
}
