problem with show hide toggle and .next()

problem with show hide toggle and .next()

I've got the following working on a menu where I have links: a class="show" followed by div class="showme"

it works toggling all divs at once but when I try to use next() I get nothing - I can't see what could be wrong:
(the //commented out bit is the next() attempt which doesn't work)
  1. <script type="text/javascript">
     jQuery(document).ready(function() {
        jQuery("a.show").click(function(){
        jQuery(".showme").slideToggle(500);
    //    jQuery(this).next(".showme").slideToggle(500);
        return false;
        });
     });
    </script>







hope someone can see where I've gone wrong here..
thanks in advance
