MC.onrelease problem for dynamic thumbnail gallery


function buildList(){ 
i=-1; 
	while (++i <= pics.length-1){ 
		spacing = 130; 
		x = spacing * i; 
		name = "name" + i; 
		display.list.attachMovie("placeholder",name,i); 
		display.list[name].loadMovie("http://www.cymbiance.com/pics/" + pics*); 
		display.list[name]._x=x; 
		display.list[name].myNum = i; 
->PROB1			display.list[name].onRelease=function(){ 
				_root.bigPlaceholder.loadMovie("http://www.cymbiance.com/pics/"+pics[this.mynum]); 
	} 
			display.list[name].onEnterFrame=function(){ 
->PROB2				percent = (this.getBytesLoaded()/this.getBytesTotal())*100;   
					if(percent == 100){ 
						setProperty (this,_width,2); 
						setProperty (this,_height,3); 
						setProperty (this,_alpha,0); 
->PROB3							for(i=0;i<100;++i){ 
								this._alpha+=1; 
		} 
	  } 
	} 
  } 
} 


ok, heres my script. the problem (the immediate problem) is that my MC.onrelease=function does not work at all. i have a links page that uses basically the same script, and it works great…maybe someone can shed some light?

thanx a lot
