I created the cart on the page and simply deleted the carriage row but have not added or deleted any other columns or anything like that. Basically left most stuff as the default. I have looked at line 28 on the relevant php file and it is this one:
$OldTheatrePosters->Display_Discounts = WA_eCart_DisplayMoney($OldTheatrePosters, $OldTheatrePosters->GetDiscounts());
I thought the best thing to do would be to send you a screenshot of each page and also of the JSON.php file. Maybe something will jump out at you - I have no doubt I am doing something wrong but can't understand what. Sorry about all this
