How to Remove a Movie Clip

Question

Hi,
On the main timeline, I have the following code:
external_btn.addEventListener(MouseEvent.CLICK, showMenu);
function showMenu(e:MouseEvent):void
var myMovieClip:MovieClip = new Member();
addChild(myMovieClip);
myMovieClip.x = 597.95;
myMovieClip.y =359.15;
in the internal movie clip, that I linked it to Member:
In the member movie clip, I have the following code to remove the movie clip that was created in the main timeline of the root movie clip.
release1_btn.addEventListener(MouseEvent.CLICK, goBack1);
function goBack1(e:MouseEvent):void
MovieClip(root).removeChild(myMovieClip);
I received the following compiler error:
1120: Access of undefined property myMovieClip.
Please help me know how to resolve this error message.
Thanks,
Robert.

Answer 1

that's (coding on more than one timeline) not good coding style, but this will correct your error and the prevent a few more:
release1_btn.addEventListener(MouseEvent.CLICK, goBack1);
function goBack1(e:MouseEvent):void
MovieClip(this.parent).removeChild(this);
