    if ( isset( $_POST['abn'] ) && ! empty( $_POST['abn'] ) ) {
          $abn = sanitize_text_field( $_POST['abn'] );
          $existing_user = get_users( array(
                        'meta_key' => 'abn',
                         'meta_value' => $abn, 
                          'fields' => 'ID',
           ) );
