v151 Whats new sidebox to display 6 most recent items

Just wondering how to get the whats new sidebox to display the 6 most recent items added to my store?

This is the link to my site : https://www.toyzeum.com/store/

the sidebox displays old items ive added but not in the order of the most recent added.... and for some reason it only displays 3 products instead of 6 products. Can anyone tell what is wrong within the script?

the code I am using as follows:

"<?php
/**
* whats_new sidebox - displays a random "new" product

*/

// display limits
// $display_limit = zen_get_products_new_timelimit();
// $display_limit = zen_get_new_date_range();
$orderBy = 'order by p.products_date_added desc LIMIT 0 , 6';
$random_whats_new_sidebox_product_query = "select p.products_id, p.products_image, p.products_tax_class_id, p.products_date_added, p.products_price, pd.products_name,
p.master_categories_id
from (" . TABLE_PRODUCTS . " p
left join " . TABLE_PRODUCTS_DESCRIPTION . " pd on p.products_id = pd.products_id )
where p.products_id = pd.products_id
and pd.language_id = '" . (int)$_SESSION['languages_id'] . "'
and p.products_status = 1 " . $orderBy;

// $random_whats_new_sidebox_product = zen_random_select($random_whats_new_sidebox_product_query);
$random_whats_new_sidebox_product = $db->ExecuteRandomMulti($random_whats_new_sidebox_product_query, MAX_RANDOM_SELECT_NEW);

if ($random_whats_new_sidebox_product->RecordCount() > 0 ) {
require($template->get_template_dir('tpl_whats_new.php',DIR_WS_TEMPLATE, $current_page_base,'sideboxes'). '/tpl_whats_new.php');
$title = BOX_HEADING_WHATS_NEW;
$title_link = FILENAME_PRODUCTS_NEW;
require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,'common') . '/' . $column_box_default);"

the sidebox displays old items ive added but not in the order of the most recent added.... and for some reason it only displays 3 products instead of 6 products. Can anyone tell what is wrong within the script?
