Can anyone tell me why this isn't working? I'm learning actionscript and my first lesson isn't working. I made a movie clip with the instant name 'mcQuit'.

mcQuit.onPress = function():Void {
trace("Why isn't this working?")
};

In this case the lessons from Lynda.com are created from MX and I'm using 8, is there an actionscript conflict here?

I have a single frame movie with the movie clip instant one the one and only frame.
