Why isnt this working?

On the main timeline

//Creating Empty MovieClip
this.createEmptyMovieClip(“holder_mc”, this.getNextHighestDepth());
//Create Listener
var mclListener:Object = new Object();
//Create MovieClip Loader
var holder_mcl:MovieClipLoader = new MovieClipLoader();
//Add Listener
this.addListener(mclListener);

holder_mc._x = 0;
holder_mc._y = 0;

frame 68 of main timeline

this.holder_mcl.loadClip(“step1.swf”, holder_mc);

In the step1. swf I have two buttons here is the script

_parent.mcwireless.btnno.onRelease = function():Void {
_parent.addListener(mclListener);
_parent.holder_mcl.loadClip(“step1-1.swf”,holder_mc);

Step1.swf loads just fine on the main timeline. However I can not load ‘step1-1.swf’ (with a button) to save my life. I thought maybe the scope was wrong but it doesn’t appear to be. Any suggestions?
