Need help with a JS fader menu

[ehoffm03]

Hi there-
Got this fading jquery menu/content code from here:

http://css-tricks.com/learning-jquer...acing-content/

Works great, but I can't get more than three to work (the demo had three) and even though I've renamed things and matched up with button name with the content div names, the content divs past the first three don't appear. Or if someone knows of an easier way to get this effect, that'd be awesome too. Thanks in advance!

Code pasted here and if you want to see it in action:

JAVASCRIPT:
<script type="text/javascript">

$(function(){

$("#page-wrap div.button").click(function(){

$clicked = $(this);

// if the button is not already "transformed" AND is not animated
if ($clicked.css("opacity") != "1" && $clicked.is(":not(animated)")) {

$clicked.animate({
opacity: 1,
}, 400 );

// each button div MUST have a "xx-button" and the target div must have an id "xx"
var idToLoad = $clicked.attr("id").split('-');

//we search trough the content for the visible div and we fade it out
$("#content").find("div:visible").fadeOut("fast", function(){
//once the fade out is completed, we start to fade in the right div
$(this).parent().find("#"+idToLoad[0]).fadeIn();
})
}

//we reset the other buttons to default style
$clicked.siblings(".button").animate({
opacity: 0.3,
borderWidth: 1
}, 400 );

});
});

</script>
