Morning, Ray ... sorry to bother you, but the above issue with updating quantity seems to still exist on mobile - I change the quantity, hit Go and the update button shows for a second before reverting to product details page without updating the number. You added a script, but I am not sure if I downloaded the amended cart.php to my local folder before working on the page ... I may have uploaded over it (?). I fixed the (1=1) problem, but can't get the update to work. Would you have a moment to help again? Thanks so much.
