I'm attempting to use the activeSlide class in the Cycle plugin, but I can't seem to get it to work properly using existing markup for the pager.

This is the code that I started with, and it works just fine (thanks to pritaeas.net):

<style type="text/css"> 
	#nav { margin: 5px; }
	#nav a { margin: 5px; padding: 3px 5px; border: 1px solid #ccc; background: #fff; text-decoration: none }
	#nav a.activeSlide { background: #f00; }
	#nav a:focus { outline: none; }
</style> 
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> 
<script type="text/javascript" src="js/jquery.cycle.all.min.js"></script> 
<script type="text/javascript" src="js/cufon-yui.js"></script>
<script type="text/javascript" src="font/MTRCT_400.font.js"></script>

<script type="text/javascript">
	Cufon.replace('#nav a', { fontFamily: 'MTRCT' ,hover: true});
</script>

<script type="text/javascript"> 
	$(function() {
		$('#slideshow').cycle({
			speed:       200,
			timeout:     0,
			pager:      '#nav',
			prev:		'#prev',
			next:		'#next',
		});
	});
</script> 
</head> 
<body> 
<div id="main"> 
	<div class="testWrapper">
		<div id="nav"></div>
	</div> 
	<div id="slideshow" class="pics"> 
		<img src="images/art_001.jpg" /> 
		<img src="images/art_002.jpg" /> 
		<img src="images/art_003.jpg" /> 
	</div> 
</div>

But, the changes that I've made below that accommodate the page I'm designing break the activeSlide, even though the pager and previous/next function perfectly:

<style type="text/css"> 
	#nav { margin: 5px; }
	#nav a { margin: 5px; padding: 3px 5px; border: 1px solid #ccc; background: #fff; text-decoration: none }
	#nav a.activeSlide { background: #f00; }
	#nav a:focus { outline: none; }
</style> 
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> 
<script type="text/javascript" src="js/jquery.cycle.all.min.js"></script> 
<script type="text/javascript" src="js/cufon-yui.js"></script>
<script type="text/javascript" src="font/MTRCT_400.font.js"></script>

<script type="text/javascript">
	Cufon.replace('#nav a', { fontFamily: 'MTRCT' ,hover: true});
</script>

<script type="text/javascript"> 
	$(function() {
		$('#slideshow').cycle({
			speed:       200,
			timeout:     0,
			pager:      '#nav',
			prev:		'#prev',
			next:		'#next',
			pagerAnchorBuilder: function(idx, slide) { 
				return '#nav li:eq(' + (idx+1) + ') a';
			}
		});
	});
</script> 
</head> 
<body> 
<div id="main"> 
	<div class="testWrapper">
		<div id="nav">		
			<ul>
				<li><a href="" id="prev">Prev</a></li>
				<li><a href="">1</a></li>
				<li><a href="">2</a></li>
				<li><a href="">3</a></li>
				<li><a href="" id="next">Next</a></li>
			</ul>
		</div>
	</div> 
	<div id="slideshow" class="pics"> 
		<img src="images/art_001.jpg" /> 
		<img src="images/art_002.jpg" /> 
		<img src="images/art_003.jpg" /> 
	</div> 
</div>

I would really appreciate some help in figuring this out.
