Please help me with a simple flash game problem

Question

I am trying to learn how to make flash games with Adobe flash 5.5. I am doing a tutorial from a book and am stuck.
The game is called concentration and you are suppose to match 2 tiles of the same shape. there are 10 shape tiles
and 1 question mark tile. These tiles are held in an array. 20 tiles are suppose to be displayed 5 to a row with 4 rows
and the question mark is suppose to be up on all 20. My problem is I get a blank screen when I test the movie. I
think the code is good but I beleive I have not uploaded the tiles right. I did upload the 11 tiles to the library and have
those 11 tiles and tile_movieclip in the library. Here is the code:
package {
// importing classes
import flash.display.Sprite;
// end of importing classes
public class Main extends Sprite {
public function Main() {
// variables and constants
const NUMBER_OF_TILES:uint=20;
const TILES_PER_ROW:uint=5;
var tiles:Array=new Array();
var tile:tile_movieclip;
// end of variables and constants
// tiles creation loop
for (var i:uint=0; i<NUMBER_OF_TILES; i++) {
tiles.push(Math.floor(i/2));
trace("My tiles: "+tiles);
// end of tiles creation loop
// shuffling loop
var swap,tmp:uint;
for (i=NUMBER_OF_TILES-1; i>0; i--) {
swap=Math.floor(Math.random()*i);
tmp=tiles[i];
tiles[i]=tiles[swap];
tiles[swap]=tmp;
trace("My shuffled tiles: "+tiles);
// end of shuffling loop
// tile placing loop
for (i=0; i<NUMBER_OF_TILES; i++) {
tile=new tile_movieclip();
addChild(tile);
tile.cardType=tiles[i];
tile.x=5+(tile.width+5)*(i%TILES_PER_ROW);
tile.y=5+(tile.height+5)*(Math.floor(i/TILES_PER_ROW));
tile.gotoAndStop(NUMBER_OF_TILES/2+1);
// end of tile placing loop
Can someone please explain to me what I am suppose to do to make the this work? I beleive the problem is it doesnt know where the tiles are.
Thanks.

To create the tiles, draw 10 distinct shapes in the first 10 frames of your symbol, and
the back of the tile in the 11th frame. You are free to draw them as you want, but I suggest you make them as 90 pixels squares with registration point (starting x and y position) at 0, because these are the properties of the tiles used in this chapter's
examples. At least, they should all be the same size.
It didnt say put in a library. It is saying to draw them in frames of symbol but it didnt walk me through that. Can you guide me through this? I also was looking at how to add the link identifier but it said I need a popup window but I cant see one. I thought that was done
when I went to insert new symbol. It said something about actionscript linkage. I am familliar with perl, java and c++ so I can follow the code so far but I dont have much understanding of the flash interface. I made the 10 shape tiles and the 1 question mark tile
in paint. They are .jpeg images.
