what i successfully did was having a button open and close a movie clip and if you changed frame that it close by default.

> helpButton.addEventListener(MouseEvent.CLICK, clickHandler);

var isThere:Boolean = false;  
var mcHandle:MovieClip = new dahelpbox();

//position the textbox eli  
mcHandle.x = 80;  
mcHandle.y = 750;

function clickHandler(e:MouseEvent):void {  
if (!isThere) {  
addChild(mcHandle);  
isThere = !isThere;  
} else {  
removeChild(mcHandle);  
isThere = !isThere;  
}  
}

newButton.addEventListener(MouseEvent.CLICK, onClick);

function onClick(event:MouseEvent):void {  
if (isThere) {  
removeChild(mcHandle);  
isThere = !isThere;  
gotoAndStop(10);  
} else {  
gotoAndStop(10);  
}  
}

\*\*\*\* Issue occurs when i try to have button A open/close movieclip A; as button B open/close movieclip B  
new code i wrote…

> green\_btn.addEventListener(MouseEvent.CLICK, GreenClick);  
> red\_btn.addEventListener(MouseEvent.CLICK, RedClick);  
> help\_btn.addEventListener(MouseEvent.CLICK, ClickHandler);  
> text\_btn.addEventListener(MouseEvent.CLICK, ClickHandler2);

var isThere:Boolean = false;  
var isDhere:Boolean = false;  
var mcHandle:MovieClip = new popbox();  
var mcHandler:MovieClip = new popper();

mcHandle.x = 500;  
mcHandle.y = 250;  
mcHandler.x = 200;  
mcHandler.y = 500;

function ClickHandler(event:MouseEvent):void {  
if (!isThere) {  
addChild(mcHandle);  
isThere = !isThere;  
} else {  
removeChild(mcHandle);  
isThere = !isThere;  
}  
}

function ClickHandler2(event:MouseEvent):void {  
if (!isDhere) {  
addChild(mcHandler);  
isDhere = !isDhere;  
} else {  
removeChild(mcHandler);  
isDhere = !isDhere;  
}  
}

function GreenClick(event:MouseEvent):void
