Modding Help HELP!!

FIXED! This monster boss I made doesn't die even when it's at 0 HP. I do I fix this! HELP!

 

Found the problem;

Code:

      {
        "title": "setDying",
        "type": "action",
        "name": "setDying",
        "parameters": {
          "shouldDie": {"value": false}
        }
      },

The "shouldDie" value was set to false, I just set it to true and now it works.
