MyHungerGames Itemconfig

It give me this
#
#  example:
#    inherits: example1
#    DIAMOND_PICKAXE,1:
#      stack-size: 1
#      # chance is not needed, without it, it defaults to 1/3.
#      # 1 is always, 0 is never
#      chance: .5
#    DIAMOND_PICKAXE,2:
#      stack-size: 1
#      chance: 1
#      DURABILITY: 3

global:
  use-match-material: true
rewards:
  max-random: 5

Then I add all of this stuff:
chest-loot:
  example:
    inherits: example1
    DIAMOND_PICKAXE,1:
      stack-size: 1
      chance: .5
    DIAMOND_PICKAXE,2:
      stack-size: 1
      chance: 1
      DURABILITY: 3

global:
  use-match-material: true
rewards:
  max-random: 5

And when I reload the server, it rejects it and goes back the way it was at the start.
