I’m trying to make a button that when u click once, the movieclip will be removed and second time back on stage and so forth…

# somehow i get this error

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.  
at flash.display:DisplayObjectContainer/removeChild()  
at sample\_fla::MainTimeline/btnClick()

==================================

Anyone can help me with this, since I’m doing an interactive web for client and the deadline is near… thanks in advance.

these are my code:

///////////////////////////////////////////////////

stop();

var swf:MovieClip;  
var loader:Loader= new Loader();  
var defaultswf:URLRequest= new URLRequest("./newSwfImport.swf");  
//default swf when loaded

loader.load(defaultswf);

//add to stage  
allSwfLoadHere.addChild(loader);  
var boolean:Boolean = true ;

function btnClick(event:MouseEvent):void {

if(boolean == true){  
allSwfLoadHere.removeChild(loader);  
boolean == false  
}

if(boolean ==false){  
allSwfLoadHere.addChild(loader);  
boolean == true  
}  
}

newSwfImport.addEventListener(MouseEvent.CLICK,btnClick);
