<p>Do anybody see problem here? It's not working.  </p>

<pre><code>$('#div1').hover(
                function () {                       
                    $('#div2').stop().animate({ backgroundPosition : '(0 -60px)' }, 500);                       
                    $('#div3').stop().animate({ marginRight : '-=10px;' }, 500);
                },
                function () {                   
                    $('#div2').stop().animate({ backgroundPosition : '(0 0)'}, 500);                        
                    $('#div3').stop().animate({ marginRight : '+=10px;'}, 500);
                });
