Multilayered Maps Collision Detection

[[email protected]]

Does anyone have an idea of how to make a phaser game with multiple layers, and have certain parts of those layers be able to collide betweent eh player and the layers?  This is my code so far:

for some reason, only layer 1 is can detect collisions, even if i put

this.physics.arcade.collide(player, layer2)

below "this.physics.arcade.collide(player, layer)"
