      $actions['resend_ical'] = array(
      'title' =&gt; t('Resend ical'),
      'href' =&gt; 'ical?' . $submission-&gt;data[5][0] . '&amp;' . $submission-&gt;data[6][0] . '&amp;' . $submission-&gt;data[35][0] . '&amp;' . $submission-&gt;data[36][0] . '&amp;' . $submission-&gt;data[24][0] . '&amp;' . $submission-&gt;data[34][0] . '&amp;' . 'node/' . $node-&gt;nid . '/submission/' . $submission-&gt;sid ,
      'query' =&gt; drupal_get_destination(),
    );
  }
