FlashCS6 - Actionscript 3 - Loading SWFs - All playing but one - actionscript-3

Question

I'm just playing around trying to get a navigation bar to work and I'm having a spot of trouble. I've got a main.swf, and inside it is code to load in a circle.swf, square.swf and triangle.swf on their respective button clicks. The circle and square load in and play correctly, however the triangle loads, but doesn't play for some reason. The code, to my eye, is the same for all three, but only that one doesn't play.
Note sure where exactly the bug might be, but below it the code referring to the specific swfs. Let me know if it's helpful to see more though.
var _swfPathArr:Array = new Array("Subfolder/Circle.swf", "Subfolder/Subsubfolder/Square.swf", "Triangle.swf");
and
button_Circle.addEventListener(MouseEvent.CLICK, setContent);
button_Square.addEventListener(MouseEvent.CLICK, setContent);
button_Triangle.addEventListener(MouseEvent.CLICK, setContent);
And the method actually displaying and clearing the loaded swfs:
function setContent(event:MouseEvent):void
{
var _swfToAdd:MovieClip;
switch(event.target.name)
{
case "button_Circle":
_swfToAdd = _swfClipsArr[0];
gotoAndStop(2);
break;
case "button_Square":
_swfToAdd = _swfClipsArr[1];
gotoAndStop(3);
break;
case "button_Triangle":
_swfToAdd = _swfClipsArr[2];
gotoAndStop(4);
break;
}
Window_content.removeChildAt(Window_content.numChildren - 1);
Window_content.addChild(_swfToAdd);
}
Any help you can offer would be greatly appreciated.
EDIT:
All the code
import flash.display.MovieClip;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.IEventDispatcher;
import flash.events.ProgressEvent;
import flash.events.Event;
import flash.events.MouseEvent;
var _swfLoader:Loader;
var _swfRequest:URLRequest;
var _swfPathArr:Array = new Array("Subfolder/Circle.swf", "Subfolder/Subsubfolder/Square.swf", "Triangle.swf");
var _loadedSWFs:int;
var _swfClipsArr:Array = new Array();
var _swfTempClip:MovieClip;
startLoading(_swfPathArr);
function startLoading(pathArr:Array):void
{
_swfLoader = new Loader();
_swfRequest = new URLRequest();
addChildAt(_swfLoader, 0);
_loadedSWFs = 0;
loadSWF(pathArr[0]);
}
function loadSWF(path:String):void
{
setUpListeners(_swfLoader.contentLoaderInfo);
_swfRequest.url = path;
_swfLoader.load(_swfRequest);
}
function setUpListeners(dispatcher:IEventDispatcher):void
{
dispatcher.addEventListener(Event.COMPLETE, onSwfComplete);
dispatcher.addEventListener(ProgressEvent.PROGRESS, currentSwfProgress);
}
function currentSwfProgress(event:ProgressEvent):void
{
var _perc:int = (event.bytesLoaded / event.bytesTotal) * 100;
//swfPreloader.precentTF.text = _perc + "%";
}
function onSwfComplete(event:Event):void
{
event.target.removeEventListener(Event.COMPLETE, onSwfComplete);
event.target.removeEventListener(ProgressEvent.PROGRESS, currentSwfProgress);
_swfTempClip = event.target.content;
_swfTempClip.customID = _loadedSWFs;
_swfClipsArr.push(_swfTempClip);
if(_loadedSWFs < (_swfPathArr.length - 1))
{
_loadedSWFs++;
loadSWF(_swfPathArr[_loadedSWFs]);
}
else
{
_swfLoader.unloadAndStop();
_swfLoader = null;
onCompletePreloading();
}
}
function onCompletePreloading():void
{
button_Circle.addEventListener(MouseEvent.CLICK, setContent);
button_Square.addEventListener(MouseEvent.CLICK, setContent);
button_Triangle.addEventListener(MouseEvent.CLICK, setContent);
}
function setContent(event:MouseEvent):void
{
var _swfToAdd:MovieClip;
switch(event.target.name)
{
case "button_Circle":
_swfToAdd = _swfClipsArr[0];
gotoAndStop(2);
break;
case "button_Square":
_swfToAdd = _swfClipsArr[1];
gotoAndStop(3);
break;
case "button_Triangle":
_swfToAdd = _swfClipsArr[2];
gotoAndStop(4);
break;
}
Window_content.removeChildAt(Window_content.numChildren - 1);
Window_content.addChild(_swfToAdd);
//trace(_swfToAdd.customID);
}
stop();
So thanks to Cherniv suggesting to switch the order of the SWFs and see what happens, it seems the problem is related to the third element in the path array. Just need a pair of outside eyes to look over the code and they'll probably be able to spot some very obvious reason for my trouble, haha. If anybody can spot it, that would be greatly appreciated.
