Help with Essentials Kits

Need help here, every time I try to create a kit in the Essentials plugin it gives me the error: "Error: That kit does not exist or is improperly defined." Can anyone help? Here is the kits part of my config.yml file:

Code:

# Note: All items MUST be followed by a quantity!
# All kit names should be lower case, and will be treated as lower in permissions/costs.
# Syntax: - itemID[:DataValue] Amount [Enchantment:Level]..
# Times are measured in seconds.
kits:
  dtools:
    delay: 10
    items:
      - 277 1 efficiency:1
      - 278 1
      - 279:780 1
  tools:
    delay: 10
    items:
      - 272 1
      - 273 1
      - 274 1
      - 275 1
  banshee:
    delay: 10
    items:
      - 261 1 flame:1
      - 262 64
      - 262 64
