Components doesnt follow my MC

m trying do a mailform, but when I use this code the components that im using doesnt show. the mail_mc is there, but not the components, why is that?


onClipEvent (enterFrame) { 
    if (_root.btn_1, hitTest(_root.head)) { 
        _root.attachMovie("mail", "mail_mc", 61); 
        _root.mail_mc._x=400; 
        _root.mail_mc._y=300;  
     
    } else { 
        unloadMovie(_root.mail_mc); 
    } 
}
