Simple Chat application sample code

Hi Folks,

I was trying out this sample code from the e-book: ‘Learning Flash Media Server 3’. I think I have followed everything, from code to setup, for what was mentioned for this code, yet it’s not working. Instead of seeing a ‘Text Area’, ‘Input Text’ and a ‘Button’ I am seeing a blank swf and there are no complier errors or anything. I am not sure what is wrong, I hope someone can advise. I am using FMS 3.5 and the following are the code and instructions for the sample code:

Follow these steps to create the application:

[LEFT]1. Open a new Flash file (ActionScript 3.0) and save it as TextSO.fla.[/LEFT]

[LEFT]2. Open the Library panel (press Ctrl+L (Windows) or Command+L (Mac OS)) and
drag a TextArea, InputText, and Button component into the Library. Save the file
again.[/LEFT]

[LEFT]3. Open a new ActionScript file and save it as TextSO.as.[/LEFT]

  1. Enter the script in Example 4-3 and resave the file.

                 textArea.setSize (200,300);

                 button.addEventListener (MouseEvent.CLICK,sendMsg);
                 addChild (button);
                 //rtmpGo = "rtmp://192.168.0.11/basicSO";
                 rtmpGo = "rtmp:/basicSO";
                 nc = new NetConnection( );
                 nc.connect (rtmpGo);
                 nc.addEventListener (NetStatusEvent.NET_STATUS,doSO);

            if (good)
            {
                  //Set up shared object
                  text_so=SharedObject.getRemote("test",nc.uri,false);
                  text_so.connect (nc);
                  text_so.addEventListener (SyncEvent.SYNC,checkSO);
            }
      }[/LEFT]
 
 
[LEFT]      private function checkSO (e:SyncEvent):void
      {
            for (var chng:uint; chng<e.changeList.length; chng++)
            {
                  switch (e.changeList[chng].code)
                  {
                        case "clear" :
                        break;[/LEFT]
 
[LEFT]                        case "success" :
                        trace (text_so.data.msg);
                        break;[/LEFT]
 
[LEFT]                        case "change" :
                        textArea.appendText (text_so.data.msg + "
");
                        break;
                    }
             }
      }[/LEFT]
 
 
[LEFT]      private function sendMsg (e:MouseEvent):void
      {
            text_so.setProperty ("msg",textInput.text);
            textArea.appendText (textInput.text + "
");
       }
     }
}[/LEFT]

The above are the instructions and code and I have done all of them. I have also placed a folder callded ‘basicSO’ in the ‘Flash Media Server 3.5\applications’ folder. I am not sure why it’s not working. I hope someone can advise. Thanks.
