I just installed this mod today, and it is simple and wonderful. A few problems though.
I am using OS2 MS2.
I notice that when I change the Price(ex) that it changes the Price(inc) and Total(inc), However the Total changes to $0.00. It also shows as $0.00 for the Order Total on the orders.php page and on the orders.php...&action=edit page, also when the customer views account.php and account_history_info.php.
Is this just me or has anyone else had this problem?
