Preloader bar not working

1

The preloader does work but the bar doesn’t work when the first image is loaded.

here is the code and a link to the gallery

MovieClip.prototype.loadPic = function(pic, id) {
    info.text = "";
    this._alpha = 0;
    this.loadMovie(pic);
    temp = this._parent.createEmptyMovieClip("temp2", 998);
    temp.onEnterFrame = function() {
        
        var total = _root.containerMC.getBytesTotal();
        var loaded = _root.containerMC.getBytesLoaded();                
        bar._visible = true;
        per = Math.round((loaded/total)*100);
    
        if (total != 0 && Math.round(loaded/total) == 1 && _root.containerMC._width != 0 && _root.containerMC._height != 0) {
            var w = _root.containerMC._width+spacing, h = _root.containerMC._height+spacing;
            _root.border.resizeMe(w,h,id);
            _root.bar._visible = false;
            _root.loadText._visible = false;
            delete this.onEnterFrame;
        } else {
            _root.bar._width = per;
            _root.loadText.text = per;
        }
    };
};
