1120: Accès des _stop de propriété non définie

Question

j'ai problème dans la création d'un lecteur vidéo en flash via AS3, le problème est que chaque fois que je tente de compiler le projet, l'erreur du compilateur indique:

1120: Access of undefined property _stop. 
1120: Access of undefined property _pause. 
1120: Access of undefined property _play. 
1180: Call to a possibly undefined method Button. 
1120: Access of undefined property _prev. 
1180: Call to a possibly undefined method Button. 
1120: Access of undefined property _next. 

Et ce continue à aller autant que j'ai mentionné ces objets, alors s'il vous plaît aidez-moi à résoudre ce problème. et je suis un débutant donc un peu difficile pour moi de trouver l'erreur.

AS3:

function SoundVolume($e:MouseEvent):void

     _sound.label = "Sound Off"; 
    } 

    _soundTransform.volume = _volume; 
    _netstr.soundTransform = _soundTransform; 
} 

Init(); 
SetupVideo(); 
SetupButtons(); 

Et même j'ai converti ce objets à des symboles de bouton.

probablement vous avez oublié d'attribuer un nom d'instance pour les objets qui utilisés comme _stop, _pause, boutons _play etc.

Et vérifier aussi le drapeau « Exporter pour ActionScript » dans les propriétés de la bibliothèque.
