Fix the toggle button
    
    We had two issues, the JS function toggle() was in if/else statements
    which means it wasn't always included and thus not always working.
    The second issue was a missing '.', the line:
      checkboxes[i].checked = !checkboxes[i]checked;
    was meant to be:
      checkboxes[i].checked = !checkboxes[i].checked;
