Passing data through connect().

Hi, I found this example of a lobby in my flash media server book. But there's a little issue...

          var nc:NetConnection;
          var rtmpNow:String;
          var userName:String;
          var users_so:SharedObject;
          var connectName:DataProvider;
          nc=new NetConnection();
          rtmpNow="rtmp://localhost/userlist/roomlist";
          nc.addEventListener (NetStatusEvent.NET_STATUS,checkConnect);
          button.addEventListener (MouseEvent.CLICK,addName);
          connectName=new DataProvider();
          function addName (e:MouseEvent)
          {
               nc.connect (rtmpNow,textInput.text);
          }
          function listPlace (e:SyncEvent)
          {
               list.dataProvider=connectName;
               list.removeAll ();
               for (var uName:String in users_so.data)
               {//no uName found.
                     if (users_so.data[uName] != null)
                     {
                          connectName.addItem ({label:users_so.data[uName]});
                     }
               }
          }
          private function checkConnect (e:NetStatusEvent)
          {
               if (e.info.code == "NetConnection.Connect.Success")
               {
                     button.label="Connected";
                     users_so=SharedObject.getRemote("users_so",nc.uri,false);
                     users_so.addEventListener (SyncEvent.SYNC,listPlace);
                     users_so.connect (nc);
               }
          }

When I press "connect", the name in textInput.text normally will be passed and added to the list under the button. But the list stays empty and textInput.text isn't passed. Does anyone know a solution?

Really thanks,

Thomas
