Thanks Bsmither for your support, it helped. Things are now working as they should. 1.5 changes into 1.

Thanks man, but you've opened our eyes. After thourough examination we found out that php files got mixed up. The classes folder we were looking at belonged to an earlier webshop we tried by Prestashop. We have removed this application just now. And we now have found the proper php gile. We are going to look into it and hope that we are capable to implement the changes that you suggested. We will let you know how it went!!! Thanks again.

@ bsmither: On behalf of TOM, thanks for your replies. But we have faced the following: There is no folder in public.html/cubecart/classes/ named cart.classes.php There only is a folder in public.html/cubecart/classes/ named cart.php This document contains 3699 lines (comments included). This line: $this->basket['contents'][$hash]['quantity'] = $quantity; could not be found in this cart.php file. We have surched all looking for the word basket, but the file doesn't contain it. So if we cannot find the line you have mentioned, it stays impossible to change it. What's next? Regards Nollie
