title: JavaScript / jQuery  why doesn't this work?
body: <pre><code>function checkSession(){
      $.ajax({url: "session.php", success: function(data){
           if( data == 1){
               var postFilen = 'msg.php';
               $.post(postFilen, function(data){
                   $("#msg").html(data).find("#message2").fadeIn("slow")
              }
           } else {
               $('#message2').hide();
           }
      }});
  // setInterval('checkSession()',1000);
  }
  </code></pre>
  
  <p>Basically, this is checking if data is 1 in session.php, and if it is, it should run msg.php´s div #message2 in #msg</p>
