[jQuery] What I am I doing wrong? This should be quick.

// when the mouse is hovering over the category link
         $("#menu li a[id]").hover(function(){

// hide the default image and description
                $(".js_off").fadeOut("fast");

 // display the slide show section whose class matches the category
link's id
                var cat=$(this).attr('id');
                $("div.slideshow."+ cat +".ns").fadeIn("fast");

 // when the mouse leaves that category link
         },function(){

 //hide the class
                $(".slideshow").fadeOut("fast");

// display the default image
                $(".js_off").fadeIn("fast");
 });


The JS Debugger does not return any errors and everything works,
except the cycle plugin, which returns no error. I am expecting the
corresponding slide show to appear, but no luck.
