Movie clip difficulity

1

Hi and thanks for viewing this thread. I have 3 movie clips that I want to place on the stage through actionscript. The movie clips are set up in an array so they can be selected however my problem is that it seems as if they are overlapping.



var shapes:Array = new Array("square", "circle", "rectangle");
var letters:Array =new Array("alpha", "beta", "gama");
var names:Array =new Array("Barney", "Sponge Bobb", "Dora");
var myAlpha:Array=[];
var one:Number;
var two:Number;
var three:Number;
function selectalpha(){
  var minNum:Number = 0;
  //Gets the lenght of an array and returns a value
  var maxNum:Number = shapes.length;
  one = Math.ceil(Math.random()*(maxNum-minNum+1))+(minNum-1);
  //pushes the value into an array
  myAlpha.push(one);
  
   minNum = 0;
   maxNum = letters.length;
  two = Math.ceil(Math.random()*(maxNum-minNum+1))+(minNum-1);
  myAlpha.push(two);
  
   minNum = 0;
   maxNum = names.length;
  three = Math.ceil(Math.random()*(maxNum-minNum+1))+(minNum-1);
  myAlpha.push(three);
  
  pulltogether(myAlpha);
 }
trace(three);
//calls the function that will place the shapes on the stage
function pulltogether(test:Array) {
 _root.createEmptyMovieClip("Placement", 2);
 Placement.attachMovie(shapes[0],Placement.getNextHighestDepth(), {_x:0, _y:0});
 Placement.attachMovie(letters[0],Placement.getNextHighestDepth+1(), {_x:0, _y:0});
 Placement.attachMovie(names[0],Placement.getNextHighestDepth+2(), {_x:0, _y:0});
  Placement._x = 190;
  Placement._y = 50;
}

I traced my depths and I got
shapes depth=1
letters depth=1
names depth =1

For some reason if all my depths are 1 only 1 of the movie clips will display

if depth are different
shapes depth=0
letters depth=2
names depth =3

The display correctly. It seems to alternate and I don’t know how to control it.
