Heloo…

stop();

tArray = ["bear0","bear1","bear2"];
for (var i = 0; i<tArray.length; i++) {
		mythumb = attachMovie("box","box"+i,10+i);
		mythumb._x = 30+mythumb._width*i;
		mythumb._y = 10;
		var mymc = mythumb.createEmptyMovieClip("holder"+i,50+i);
		mymc.loadMovie(tArray*+".gif",99);
////////////////  only this part it's not working  //////////////
		mymc.onPress= function(){
			trace("whoopss")		
		}
//////////////////////////////////////////////

}
