function scale_collection_form_validate($form, &$form_state) {

  // If the user is trying to create a new collection
  if (drupal_strlen($form_state['values']['collectionnew']['alternative0']) > 0) {

    // If the new collection don't have two alternatives
    if (drupal_strlen($form_state['values']['collectionnew']['alternative1']) == 0) {

      // This can't be replaced by adding #required to the form elements. If we did so we would always have to
