help with simpe hover, please

Hello All,
I have a very simple hover function that I cannot seem to get to function correctly,
I need to have a div show up over the current hovered div. An overlay. Its for blog postings. IAnytime I hover over one, all of the overlay divs show up. What am I missing?

here's the jQuery:
  1.     $('div.post-overlay').hide();
        $('div#excerpt-wrap').hover(
            function(){
                $('div.post-overlay').show();
            },
            function(){
                $('div.post-overlay').hide();
            }






And the HTML(snippet)
  1.  <div id="post-63" class="homepost">
     <h1 class="title"><a href="http://obeliskwebdesign.com/sandbox/blogs/vc/?p=63" title="Post for Archives to show two months">Post for Archives to show two months</a></h1>

     
     <div class="entry no-image">
     <a class="post-hover" href="http://obeliskwebdesign.com/sandbox/blogs/vc/?p=63#more-63" title="Post for Archives to show two months">
     <div id="excerpt-wrap">
     <div class="post-overlay"><!-- shows when #excerpt-wrap is hovered -->
     
     </div>
     <!-- /// end div.post-overlay -->
