movieClip.onRelease ?help needed!

[size=2][left] [/left]

 for (i=0; i<3; i++){
 createEmptyMovieClip("holder"+i, i);
 loadMovie(i+1+".jpg", "holder"+i);
// loadMovie(i+1+".jpg","holder"+i);
 setProperty("holder"+i, _y, "0");
 setProperty("holder"+i, _x, "40"*i);
 this["holder"+i].onPress = function (){

[size=2][/size][size=2] [/size]
