[jQuery] A simple loop - but I can't do it

[jQuery] A simple loop - but I can't do it

<html>
<body>
Hi folks,
I have a form (id="sshoweditor") containing - let's say 6 -
fieldsets, each containing an input element.
The fieldsets have a unique ID - fs0, fs1, ... fs5.
I have a function that can delete any specific fieldset.
My looping problem comes now - when the fieldset is removed, I want to
renumber the remaining fieldsets.
<tt>
$("#fs"+ej).highlightFade({color:'yellow',speed:2000,iterator:'sinusoidal'}).animate({opacity:
1.0}, 1000).fadeOut(500).remove();
var n = parseInt($("#howmany").attr("value"))-1;
$("#howmany").attr("value",n);
var z = 0;
$("#sshoweditor fieldset").each(function(t){
  ( { "id" : "fs" + z} );
   z=z+1;
  });
</tt>My code doesn't throw an error - but it doesn't produce a result
either.  Can someone guide me here.
Thanks
