Excellent. Thanks. I think I follow what you have done. But to clarify,
and learn, what are you doing with -= ?
$trolley[$item] -= $quantity;
Likewise, i had not followed what you were doing with the lines I
commented out. They did not seem to work, and I succeeded in doing what
I wanted without them. I'm a prof, as you can tell, and always have a
question for an answer ;).
Thanks for your time and patience,
John
