Online Group Pricing error

[jrhame]

I am recieving an error ONLY when I add a special. Otherwise the mod is working flawlessly.
The error

Fatal error:  Call to undefined function:  () in /home/virtual/site83/fst/var/www/html/zen_cart/includes/functions/functions_prices.php on line 209

Line 209, plus a little extra

$display_normal_price = round(zen_display_group_pricing($display_normal_price,$products_qty),2);
    
    if (SHOW_SALE_DISCOUNT_STATUS == '1' and ($display_special_price != 0 or $display_sale_price != 0)) {
      if ($display_sale_price) {
        if (SHOW_SALE_DISCOUNT == 1) {
          if ($display_normal_price != 0) {

////////////////////// line 209///////////////////////////////////////////////////////
       
$show_discount_amount = $number_format(100 - (($display_sale_price / $display_normal_price) * 100),SHOW_SALE_DISCOUNT_DECIMALS);

//////////////////////////////////////////////////////////////////////////////////////

          } else {
            $show_discount_amount = '';
          }
          $show_sale_discount = '<span class="productPriceDiscount">' . '<br />' . PRODUCT_PRICE_DISCOUNT_PREFIX . $show_discount_amount . PRODUCT_PRICE_DISCOUNT_PERCENTAGE . '</span>';

This is the only thing I need to fix before I start skinning the site, help!

I also am getting the same error when I do a SaleMaker.

I got it.
Take out the $ before number_format :)
