Hi, I have very little knowledge about php...
I'm having a slight problem with installing a Quantity Discount contribution to the osmax 1.7. It works perfectly well for my public (retailer) customers but as soon as I have customers from other groups the discount does not function. I wish the discounts to be the same for each group... Here is the coding on that page... Does somebody have an idea... I imagine I should be able to change it just by playing on the position of the code concerning the quantity discounts :

Code:
$pf->loadProduct((int)$HTTP_GET_VARS['products_id'], (int)$languages_id);
    $products_price=$pf->getPriceString();
Any idea?

Thanx in advance

Code:
   if ($new_price = tep_get_products_special_price($product_info['products_id'])) {
// ***** Begin Separate price per customer mod *****
            global $customer_id;
          $customer_group_query = tep_db_query("select customers_group_id from " . TABLE_CUSTOMERS . "        where customers_id =  '" . $customer_id . "'");
          $customer_group = tep_db_fetch_array($customer_group_query);

        $scustomer_group_price_query = tep_db_query("select customers_group_price from " . TABLE_PRODUCTS_GROUPS . " where products_id = '" . (int)$HTTP_GET_VARS['products_id']. "' and customers_group_id =  '" . $customer_group['customers_group_id'] . "'");
        if ($scustomer_group_price = tep_db_fetch_array($scustomer_group_price_query))
        $product_info['products_price']= $scustomer_group_price['customers_group_price'];
// ***** Begin Separate price per customer mod *****
      $products_price = '<s>' . $currencies->display_price($product_info['products_price'], tep_get_tax_rate($product_info['products_tax_class_id'])) . '</s> <span class="productSpecialPrice">' . $currencies->display_price($new_price, tep_get_tax_rate($product_info['products_tax_class_id'])) . '</span>';
    } else {
//************Begin Separate Price per Customer mod **************

    $pf->loadProduct((int)$HTTP_GET_VARS['products_id'], (int)$languages_id);
    $products_price=$pf->getPriceString();
global $customer_id;
$customer_group_query = tep_db_query("select customers_group_id from " . TABLE_CUSTOMERS . " where customers_id =  '" . $customer_id . "'");
$customer_group = tep_db_fetch_array($customer_group_query);
$customer_group_price_query = tep_db_query("select customers_group_price from " . TABLE_PRODUCTS_GROUPS . " where products_id = '" . $HTTP_GET_VARS['products_id'] . "' and customers_group_id =  '" . $customer_group['customers_group_id'] . "'");
if ( $customer_group['customers_group_id'] != 0) {
  if ($customer_group_price = tep_db_fetch_array($customer_group_price_query)) {
    $products_price = $currencies->display_price($customer_group_price['customers_group_price'], tep_get_tax_rate($product_info['products_tax_class_id']));
  } else {
      $products_price = $currencies->display_price($product_info['products_price'], tep_get_tax_rate($product_info['products_tax_class_id']));
    }
} else {
    $products_price = $currencies->display_price($product_info['products_price'], tep_get_tax_rate($product_info['products_tax_class_id']));
  }
