Automatically updating google spreadsheet with modified dates

Question

\'ve been trying get google spreadsheet to add data into a cell automatically when another cell is edited, however I can only seem to make the onedit function work globally.

Answer 1

function onEdit(e) {
  var s = e.source.getActiveSheet();

  if( s.getIndex()== 2 ) {
    var r = s.getActiveRange();
    if( r.getColumn() == 2) {
      s.getRange(r.getRow(),14).setValue(new Date());

    }
  }
}
