I'm attempting to make a helper function which sets the turn order, but I'm falling at the first hurdle! Even though I'm using exactly the code provided by Roll20's Help docs, I'm getting an error when attempting to even get the turn order object: function setTurnOrder(value) { var turnorder; if (Campaign().get("turnorder") == "") turnorder = []; else turnorder = JSON.parse(Campaign().get("turnorder")); }; [Log] ReferenceError: Can't find variable: Campaign (sheetsandbox.bundle.js, line 3339) setTurnOrder (anonymous function) (anonymous function) — sheetsandboxworker.js:149 messageHandler — sheetsandboxworker.js:768 Any permutation of 'Campaign()' gives the same error - it's not being found, but I don't know why. Is it because the Campaign object's not accessible in some situations? Is it because I'm running the code in the Custom Sheet Sandbox and the Campaign object doesn't exist there? Please help!
