Hi,

Please open template.php file(sites\all\themes\md_hillter), then add this code:

$form['rooms_fieldset']['group_size_adults:1']['#options'][0] = t('Adults');$form['rooms_fieldset']['group_size_adults:1']['#default_value'] = 0;$form['rooms_fieldset']['group_size_children:1']['#options'][0] = t('Children');$form['rooms_fieldset']['group_size_children:1']['#default_value'] = 0;

below

$form['rooms_date_range']['rooms_start_date']['#suffix'] = '<div class="arrival element-invisible">' . t('Arrival Date') . '</div></div>';
$form['rooms_date_range']['rooms_end_date']['#suffix'] = '<div class="departure element-invisible">' . t('Departure Date') . '</div></div></div>';

Thanks!
