Can't Figure Out How to Fix This

# PermissionsBukkit configuration file
#
# A permission node is a string like 'permissions.build', usually starting
# with the name of the plugin. Refer to a plugin's documentation for what
# permissions it cares about. Each node should be followed by true to grant
# that permission or false to revoke it, as in 'permissions.build: true'.
# Some plugins provide permission nodes that map to a group of permissions -
# for example, PermissionsBukkit has 'permissions.*', which automatically
# grants all admin permissions. You can also specify false for permissions
# of this type.
#
# Users inherit permissions from the groups they are a part of. If a user is
# not specified here, or does not have a 'groups' node, they will be in the
# group 'default'. Permissions for individual users may also be specified by
# using a 'permissions' node with a list of permission nodes, which will
# override their group permissions. World permissions may be assigned to
# users with a 'worlds:' entry.
#
# Groups can be assigned to players and all their permissions will also be
# assigned to those players. Groups can also inherit permissions from other
# groups. Like user permissions, groups may override the permissions of their
# parent group(s). Unlike users, groups do NOT automatically inherit from
# default. World permissions may be assigned to groups with a 'worlds:' entry.
#
# The cannot-build message is configurable. If it is left blank, no message
# will be displayed to the player if PermissionsBukkit prevents them from
# building, digging, or interacting with a block. Use '&' characters to
# signify color codes.
