AttachMovie and Space Limit

1

hiiiiiiii,

I would like to create a grade where it contained 31 objects, however when one of these objects pass for the defined limit it was directed for the side and continued the grade. This is the code that I am using to distribute objects, but when it pass to the limit the _y keep on the same value:

this.onEnterFrame = function() {
  	for (i=0; i<32; i++) {
  		this.attachMovie("box", "box"+i, i);
  		box = this["box"+i];
  		box._y += 75*i;
  		if (box._y>=400) {
  			box._x = 400;
  			box._y = 70*i;
  		}
  	}
  };
