Ed, yes it is in the cart component, but the same code is also in the
checkout.html file in pages/ord and I have reviewed the documentation
and the parameter that suppresses the output is "hide" when set to true
(or 1).  In the code above the hide paramenter is not present and by
default is set to false.  This code should be printing the weight,
correct?
