Thanks for the reply, I have found the line of code that causes it, it is a
line in a usertag which clears all session discounts, it is this running
with nothing in the cart that causes it:-

%{$Session->{discount}} = ();

The line originates from Mike in this thread when I was having problems
clearing discounts:-


Any suggestions on how to fix this, maybe I should check the cart isn't
empty before trying to clear discounts?
