Multiplayer movement

I watched the multiplayer tutorial from youtube, and everything else works but the movement. Player isn't defined anywhere in the tutorial (which I copied word to word) but it still wants to draw the sprites at player.x and player.y.

OK, in your init, create 2 player objects like this

init = function()
//The two players are defined as objects.
  player = object
    x = -70
    y = 0
    width = 32
    height = 32
    speed = 3
  end

  player2 = object
    x = 70
    y = 0
    width = 32
    height = 32
    speed = 3
  end
end

update = function()
//the two movements
  if keyboard.UP then
    player.y += player.speed
  elsif keyboard.DOWN then 
    player.y -= player.speed
  elsif keyboard.LEFT then
    player.x -= player.speed
  elsif keyboard.RIGHT then
    player.x += player.speed
  end

  if keyboard.T then
    player2.y += player2.speed
  elsif keyboard.G then 
    player2.y -= player2.speed
  elsif keyboard.F then
    player2.x -= player2.speed
  elsif keyboard.H then
    player2.x += player2.speed
  end
end

draw = function()
//Monify the icon, not your real sprite name
  screen.clear("rgb(85,255,198)")
  screen.drawSprite("icon", player.x, player.y, player.width, player.height)
  screen.drawSprite("icon", player2.x, player2.y, player2.width, player2.height)
end
