Can someone puts me out of my misery? please!

Ok, so here is the problem

I have the main site called godsandmonsters.fla. This works just fine. Buttons, menu etc.
The site is in a movie clip

Then, I have an index.fla which is the loader

here is the action script

var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
l.load(new URLRequest(“godsandmonsters.swf”));

function loop(e:ProgressEvent):void
{
var perc:Number = e.bytesLoaded / e.bytesTotal;
percent.text = Math.ceil(perc*100).toString();
}

function done(e:Event):void
{
percent_mc.visible=false;
removeChildAt(0);
percent = null;
addChild(l);
}

But then if I publish the index.fla, I keep getting this message

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at godsandmonsters_fla::godsandmonsters_mc_1/frame1()

and then, nothing work except for the intro music.

Can someone please help

Many many thanks
