Hey,

Im trying to get my text to change depending on the playhead in another MC. This is my code… someone have a peak at what may be wrong

btn.onPress = function() {
    ball.gotoAndPlay("start");
    if (_root.ball._currentframe>2) {
        _root.txtArea.text = "Hello Ball!";
    } else if (_root.ball._currentframe<10) {
        _root.txtArea.text = "Goodbye Ball.";
    }
};
