How to make a short piece of jQuery validate?

How to make a short piece of jQuery validate?

I'm using a piece of code which is producing validation errors. It uses the '&' sign and the validators aren't happy because they want it to be ' &' - which of course validates but stops the script working.

So, here is the code, how do I keep it working but enable it to validate correctly? The problem is the double '&' signs on the fourth line after .length...
  1. <script type="text/javascript">
        $(document).ready(function(){
          $(".tab-set").tabs();
          if($(".tab-set").length && document.location.hash){
                $.scrollTo(".tab-set");
            }
          $(".tab-set ul").localScroll({
            target:".tab-set",
            duration:0,
                hash:true
            });
        });
      </script>  














Hope someone can figure this one out?
