  1. No one can help me with my problem here ? This is about the last thing I need to do before going live. Please help me !?!?
  2. Goodday, I got some very helpfull information last couple of months from this forum thank you for this guys !!! I'm setting up a online webshop for garden articles. Though I could always find my answer on this forum, now I am really stuck. I have about 90% done of my webshop and I have several contributions installed they all work as they should luckily. I am having some problems now with the Product Accessory Multiplier contribution. It all works as it should except for the sub-total in the shopping cart and in the cart info box. it is off several euro's. But only if I use a attribute with a '*' prefix. And I can't find why, I played around with the sub-total calculation line and had several results but it's never the same as the one product in the basket. All other prefixes work as they should and the sub-total is correct. It does calculate the correct prices during checkout when a '*' prefix is used, only place where it goes wrong is the shopping cart. Line 372 is where the sub-total is calculated and that's what I altered to try en error, only thing I get is error. This is the line : $this->total += (tep_add_tax($products_price, $products_tax) + $attributes_price) * $qty; Could you please help me out !?!? It be much appriciated. <?php /* $Id: shopping_cart.php,v 1.35 2003/06/25 21:14:33 hpdl Exp $ osCommerce, Open Source E-Commerce Solutions http://www.oscommerce.com Copyright (c) 2003 osCommerce Released under the GNU General Public License */ class shoppingCart { var $contents, $total, $weight, $cartID, $content_type; function shoppingCart() { $this->reset(); } function restore_contents() { global $customer_id; if (!tep_session_is_registered('customer_id')) return false; // insert current cart contents in database if (is_array($this->contents)) { reset($this->contents); while (list($products_id, ) = each($this->contents)) { $qty = $this->contents[$products_id]['qty']; $product_query = tep_db_query("select products_id from " .
