title: How to have only one box checked instead of two on Google Apps Script?
body: <pre><code>function onEdit() {
    var ss = SpreadsheetApp.getActiveSpreadsheet();
    var sheet = ss.getSheets()[1];
    if (sheet.getActiveCell() = "E11"){
      sheet.getRange('E12').activate();
      sheet.getCurrentCell().setValue('FALSE');
      sheet.getRange('E13').activate();
      sheet.getCurrentCell().setValue('FALSE');
      sheet.getRange('E14').activate();
      sheet.getCurrentCell().setValue('FALSE');
    }
    if (sheet.getActiveCell() = "E12"){
      sheet.getRange('E11').activate();
      sheet.getCurrentCell().setValue('FALSE');
      sheet.getRange('E13').activate();
      sheet.getCurrentCell().setValue('FALSE');
      sheet.getRange('E14').activate();
      sheet.getCurrentCell().setValue('FALSE');
    }
  }
  </code></pre>
  
  <p>So I want to make it so that if a TRUE statement is inputted, the other checkbox will be FALSE and viceversa.</p>
