Using TWO loaders for ONE Tree Menu

I am using a tree menu that I am loading in Print2Flash documents. There is one node on the menu I want to load a regular SWF file that will have links to animations. Because my loader is customized to load Print2Flash documents, is there a way to use a new loader to load a standard SWF on one of the Tree Menu Nodes?

I tried to put in a new loader but so far no luck, I am getting 'Incorrect number of argument. Expected no more than 1' on the case line for the new loader.

Code is below...my attempt to put in a new loader is bolded...any help?

stop();
import com.microwebber.tree.*;
import Print2Flash.*
import flash.display.Loader;
import flash.events.Event;
import flash.net.URLRequest;
import fl.events.*;

stage.align=StageAlign.TOP_LEFT

mytree.setSize(315,417);
var usingFolderIcons = false;
function  switchIcons(e){
usingFolderIcons = !usingFolderIcons;
mytree.setDefaultFolderStyle(usingFolderIcons);
mytree.invalidate();

}

//mytree.setHorizontalPolicy(true,true);
