i want to do something simple as run a command that will give everyone a supply signal, but the thing doesn't work! if you spot a problem then pls fix my mistakes!

heres the rewards.json

{
  "Groups": {
    "default": {
      "supply": "giveall supply.signal"
    }
  },
  "TopVoters": {
    "1": {},
    "2": {},
    "3": {}
  }
}​

Replace "default" with "default.1". Read the documentation carefully, don't modify the config at random.
