I need an oscommerce experienced developer to fix a calculation problem during checkout. See attachment to see the problem.
The product price with attribute shows correctly on [url removed, login to view] page. I add the product to the shopping cart and it shows correctly here as well. It is only when I go to checkout confirmation page I see that additional tax is added to the attribute so the price shows more than what it does on product page.
I am sure it is a quick fix in classes/orders.php. I had a go at it but didnt get anywhere as I am not a coder. It will be a quick fix for you. The quicker the fix is the better chances we will be working again on another project as I have plenty of work for oscommerce developers.
