Learning OOP?

1

I am learning OOP and have a question. On my stage I added a dynamic text field with instance name “test”. In my class I have the following:


package {
    import flash.display.MovieClip;
    public class Main extends MovieClip {
        public function Main() {
            trace("Flash");
            test.text = "Flash";
        }
    }
}

I get an output error 1046: Type was not found or was not a compile-time constant: TextField.

What am I doing wrong here?
