whats wrong with this that preloading(tfPercentage)ends up with NaN error

contArr = [  
“00.jpg”,  
“01.jpg”,  
“02.jpg”  
];

function preloadClips (nr) {  
var cnt = this.createEmptyMovieClip(“container”,10);  
cnt.\_visible = false;  
var ch = this.createEmptyMovieClip(“check”,11);  
ch.onEnterFrame = function () {  
var bl = this.\_parent.container.getBytesLoaded();  
var bt = this.\_parent.container.getBytesTotal();  
this.\_parent.tfPercentage.text = Math.round((bt/bl)\*100);  
if (bl/bt==1) {  
info= ("loaded " + contArr[nr]);  
this.removeMovieClip();  
this.\_parent.tfPercentage.text=0  
this.\_parent.container.removeMovieClip();  
if (this.nr\<=contArr.length) {  
preloadClips(++nr);  
this.\_parent.tfPercentage.text = “100%”;  
} else {  
return;  
}  
}  
}  
cnt.loadMovie(contArr[nr]);  
}  
preloadClips(0);
