Google sheets – Installable Triggers

by

I’m trying to run the onChange function below using triggers but keeps failing.

The error is:
TypeError: Cannot read properties of undefined (reading 'getSheet') at onChange(Code:161:21) Line 161 is var sheet = range.getSheet();

My function:

  var range = e.range;
  var sheet = range.getSheet();
  if (sheet.getName() == 'SMS' && range.getRow() > 1 && range.getColumn() < 3) {
    var colA = sheet.getRange(range.getRow(), 1).getValue();
    var colB = sheet.getRange(range.getRow(), 2).getValue();
    if (colA != '' && colB != '') {
      sheet.getRange(range.getRow(), 3).setFormula("='SMS Text'!$B$1");
    }
  }
}```

Triggers settings are:

  • The event object for onChange and onEdit trigger is a lot different.

    – 

  • You will need to replace e.range somehow because onChange does not supply a range value.

Differences in onEdit and onChange event objects

function onMyEdit(e){Logger.log(JSON.stringify(e))};
//{"authMode":"FULL","oldValue":"10.0","range":{"columnEnd":6,"columnStart":6,"rowEnd":6,"rowStart":6},"source":{},"triggerUid":"","user":{"email":"","nickname":""},"value":"pp"}


function onMyChange(e){Logger.log(JSON.stringify(e))};
//{"authMode":"FULL","changeType":"EDIT","source":{},"triggerUid":"","user":{"email":"","nickname":""}}

onChange event object does not supply a range value
