Need help with declaring var for multiple functions

hi, how to declare a variable that can be accessible for some functions, and recreatible with "new" command, using or without using packages?

Code:

---

function showWindow(event:MouseEvent):void {
        currentButton = event.target.name;
        var holder:DisplayObjectContainer=new DisplayObjectContainer();
        addChild(holder);
       
        loader = new SWFLoader("swf/showwindow.swf", {onComplete:onLoadSWF, container:holder, width:200, height:200, x:0, y:0, hAlign:"left", vAlign:"top", centerRegistration:true});
        addChild(loader.content); //add the ContentDisplay to the display list even before raw content is loaded.
        loader.load();
}

function onLoadSWF(event:LoaderEvent):void {
        mc = loader.rawContent; //the root of the child swf
        mc.close_btn.addEventListener(MouseEvent.CLICK, closeSwf);
        mc.topBar_mc.addEventListener(MouseEvent.ROLL_OVER, rollOverHandler);
        mc.topBar_mc.addEventListener(MouseEvent.MOUSE_MOVE, follow);
        mc.topBar_mc.addEventListener(MouseEvent.ROLL_OUT, rollOutHandler);

        setChildIndex(cursor_mc, numChildren-1);
        holder.x=200;
        holder.y=200;
       
        // Detect which button was clicked
        if (currentButton=="instanceCapitalLettersShow") {
                mc.show_txt.text=onCapitalClick();
        } else if (currentButton=="instanceSmallLettersShow") {
                mc.show_txt.text=onSmallClick();
        } else if (currentButton=="instanceNumbersShow") {
                mc.show_txt.text=onNumbersClick();
        }
}

my problem is two functions can't use one variable "holder". can anyone help me?

i m using greensock swfloader

youre talking about classes, thats the only thing that can be created with "new", well jsut read up about basic as3 oop

Your holder variable is declared inside showWindow, so it is local to that function. You must declare it at a higher scope in order for it to be available to other functions.

Of course, there's no reason you actually need it in the other function since you could set the x and y in the first one.
