I am trying to make the server say something when an item is sold.  May also add something when the item is bought.

"Anti-Radiation Pills": {
      "buy": "1000",
      "cmd":[
        "say $player.name is selling drugs somebody please Nerf them!!!"
      ],
      "img": "https://rustlabs.com/img/items180/barrelcostume.png",
      "item": "anti-radiation pills",
      "sell": "100"​
