Can't check collision with layer

[lehm]

Hi guys, this is my first post so if this is somewhere it's not suppose to be i'm really sorry.

I created a layer with Tiled and want to set collision between the sprite and all the tiles in the layer but it doesn't seem to work. (The map showed up and everything)

Here is my code 

  var create = function(){
    // Razor.game.add.sprite(0, 0, 'bg');
    map = Razor.game.add.tilemap('gamemap', 16, 16);
    map.addTilesetImage('tileset','tiles');
    layer = map.createLayer(0);
    layer.resizeWorld();
    map.setCollisionBetween(0, 5049);
    Razor.game.world.setBounds(0, 0, 3200, 32280);
    Razor.keyboard = Razor.game.input.keyboard;
    Razor.game.physics.startSystem(Phaser.Physics.ARCADE);

    player = new Player(window.innerWidth/2, window.innerHeight/2);

    // Razor.game.camera.follow(player);

  }

 var update = function(){

  Razor.game.physics.arcade.collide(player, layer);
