Beginner problem with Tilemaps

[DudeshootMankill]

Hey guys i've got a weird problem with tilemaps.

In the create function i've got this:

this.collisionLayer = this.map.createLayer('CollisionLayer');
this.ladderLayer = this.map.createLayer('LadderLayer');

this.collisionLayer.resizeWorld();

this.map.setCollisionByExclusion([0 ]);

and in the update function:

this.game.physics.arcade.collide(this.player, this.collisionLayer);

this works just fine, and the player collides with the collisionLayer and so on.

However if i do this:

this.game.physics.arcade.collide(this.player, this.ladderLayer);

Nothing happens. I can collide perfectly fine with the ground in my small level. But the exact same code doesnt work for the ladderLayer.

I've attached the file beneath if anyone would be so kind as to take a gander. Thanks for your time.

Disregard this.

    this.map.setCollisionBetween(0, 10000, true, this.ladderLayer);
    this.map.setCollisionBetween(0, 10000, true, this.collisionLayer);

I did this and it worked.
