[jQuery] Slide in / out message

[Snaak]

Hi all,
I try to make a div to slide down, pauze for 5 seconds and then slide
up. This is meant for showing a message. Just like the Twitter
interface. But I cannot get it working. Anyone an good idea?
Thx in advance!

Current code:
 $(".testbutton").click(function () {
      $('#test').slideDown( 'slow' );
                timer = setTimeout('$(".testbutton").click()',500);
                $('#test').slideUp( 'slow' );
                return false;
    });
