Question array and frame change

[cnnhean]

well the title is not very accurate so the Question is how i can do something like that

var h:int;
                    var horses:Array = new Array();

                for (h = 0; h < numChildren; h++) {
            if (getChildAt (h) is horse) {
            horses.push(getChildAt(h).getRect(this));
                }
            }

            for ( h=0; h<horses.length ; h++ ) {
            if (player.getRect(this).intersects(horses[h])) {
                horses[h].S.gotoAndStop(2);
              }
            }

i just cut it from the code so i hope nothing missing . so what i tried to do is whan the player touch the horse (one of many) the one he touch change to another frame.
