    Hi, this will at least get rid of the error codes for you,
    PHP Code:
    package 
    {
        
    import flash.display.MovieClip;
        
    import flash.events.KeyboardEvent;
        
    import flash.ui.Keyboard;
        
    import flash.events.Event;//used for ENTER_FRAME event

        
    public class Main extends MovieClip
        
    {
