I want to use running man with just money reward, how should the json files look like? do i edit both in text editor or can i just delete the one in data folder and use the /running command to add rewards.

Hello, you can use both /running commands to edit data file or simply unload the plugin and edit it manually

{
  "runner": {
    "Money": {
      "RewardItems": {
        "Money": {
          "MinValue": 100,
          "MaxValue": 1000
        }
      }
    }
  },
  "killer": {
    "Money": {
      "RewardItems": {
        "Money": {
          "MinValue": 100,
          "MaxValue": 1000
        }
      }
    }
  }
}​

do I need to edit the json in the config folder too to get money rewards to work?

If the data file is correctly configured, no
But I recommend to do it

ok, it says I got a money reward but I dont. How should the json in the config look like to work with money? I have economics installed and its working.
