I've got this code with a variable of platform, which I'm trying to link with the actual object of Platform in my .fla file but I get this error when I run it; ArgumentError: Error #1063: Argument count mismatch on Code(). Expected 1, got 0. In my output window.

package  {

import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.events.KeyboardEvent;
import flash.events.Event;
import flash.ui.Keyboard;


public class Code extends MovieClip {

    var charSpeed:int = 0;
    var velocity:int = 0;
    var gravity:Number = 1;
    var Jump:Boolean = false;


    public function startGame(){
         stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeyDown);
         stage.addEventListener(KeyboardEvent.KEY_UP, checkKeyUp);
         stage.addEventListener(Event.ENTER_FRAME, loop);
     }

    private var platform:Platform;

    public function Code(value:Platform) {
        platform = value;
    }

    function checkKeyDown(evt:KeyboardEvent){
        if (evt.keyCode == Keyboard.LEFT){
            charSpeed -= 10;
        }
        if (evt.keyCode == Keyboard.RIGHT){
            charSpeed += 10;
        }
        if (evt.keyCode == Keyboard.DOWN){
            if(!Jump){
                velocity -= 14;
                Jump = true;
            }
        }
    }

    function checkKeyUp(evt:KeyboardEvent){
        if (evt.keyCode == Keyboard.LEFT){
            charSpeed = 0;
        }
        if (evt.keyCode == Keyboard.RIGHT){
            charSpeed = 0;
        }
    }

    function loop(evt:Event){
        player.x = velocity;
        if (player.x < 0){
             player.x = 0;
        }
        if (player.x > 550){
             player.x = 550;
        }

        velocity += gravity;

        var Platform:Array = new Array(platform)


        if (!Platform.hitTestPoint(player.x, player.y, true)){
            player.y += velocity;
        }

        for (var i = 0; i < 10; i++){
            if (Platform.hitTestPoint(player.x, player.y, true)){
                player.y--;
                velocity = 0;
                Jump = false;
            }
        }
    }
}

}

The as3 file name is Code, and the fla file name is Game. My objective is to get my player to move around on the platform using the arrow keys. The linkage of my platform is "Platform". If anyone could help that would be great
