Simple Connect Problem

Hello,

I have created a chat application using the communication components using this tutorial
http://www.adobe.com/devnet/flashcom/articles/first_comm_app.html

I have people list component , chat component and the simple connect component in the stage.In simple connect I have given the localhost path and instance name of other components.
When I run the application the connection light TURNS GREEN indicating the connection has been established. I even have server-side script main.asc which loads the component.( load( "components.asc" );)

But, my problem is what to do after that..?

Because when I press on the login button of simple connect nothing happens!
And also, when I type something on the chat and enter nothing is displayed in the chat area.


What may be the problem?? Any ideas…??
