Hello. I need help. My code works fine, but when I change the scene with the MC "pruebadef", I get error # 1009
It is the enter_frame event that is not working well. This is the error:
TypeError: Error # 1009: Cannot access a property or method of a null object reference.
at baroqueimprovisation_fla :: MainTimeline / fl_ClickToGoToScene_24 () [baroqueimprovisation_fla.MainTimeline :: frame6: 54
this is the code.

This is the area where the error occurs (6:54)- Basically, I change the scene and remove the enterframe listener and other methods
52 function fl_ClickToGoToScene_24(event:MouseEvent):void{
53 MovieClip(this.root).gotoAndPlay(1, "Controladores");
54 playStop.removeEventListener (Event.ENTER_FRAME, botonPlayStop);
55 SoundMixer.stopAll();
56}
The enter_frame event appears when a sound is loaded:
46 function musicLoaded (event:Event):void{
47 playStop.addEventListener (Event.ENTER_FRAME, botonPlayStop);
48 aumentar.enabled = false;
49 disminuir.enabled = false;
50 }
also appears in the playStopMusic function.aparec Once
thanks!!
