removeEventListener won't work?

Hello. I am using Adobe Flash CS6.

Right now I put a AS on root that does removeEventListener to remove event listener inside  a movie clip "mcA", but it can not remove the event listener. so I put removeEventListener inside mcA and it works fine. Why? I can not remove event listener from root so if I need to remove event listener inside movie clips I should write removeEventListener   not on root but inside them?

because test is not on the root timeline.  use:

stage.addEventListener (MouseEvent.CLICK,Remove_Event);

function  Remove_Event(event:MouseEvent):void

{

mcA.mcB.removeEventListener (MouseEvent.CLICK,mcA.test);

}

//And I put this AS inside mcA.

mcB.addEventListener (MouseEvent.CLICK,test);

function  test(e:Event):void{

mcB.rotation +=5;

}

you need to remove the event listener from the correct scope after the listener has been added (and make sure it's not re-added).

so, if you used,

addEventListener("someevent",somefunction);

inside mcA and mcA is on the root timeline, you would use the following from the root timeline AFTER mcA exists and AFTER the above listener is added,

mcA.removeEventListener("someevent",somefunction);

I put a movie clip "mcA",which has a movie clip "mcB" inside, on root

and put this AS on root.

stage.addEventListener (MouseEvent.CLICK,Remove_Event);

function  Remove_Event(event:MouseEvent):void

{

mcA.mcB.removeEventListener (MouseEvent.CLICK,test);

}

And I put this AS inside mcA.

mcB.addEventListener (MouseEvent.CLICK,test);

function  test(e:Event):void{

mcB.rotation +=5;

}

And I get this error message.

1120: Access of undefined property test.

I can not access function "test" from root. Why?
