Q on variables and shipping

["Walter Torres" <walter@tscinternet.com>]

I have a questions on code from 'web_store.setup.frames.javascript'...

# The first pipe-delimited fields correspond to the
# sc_order_form_shipping_related_fields.

I first took this line to mean plural fields 'pipe-delimited fields',
then I read on down the file and read all this over again and I then
thought it was a mis-type and was actually talking about the first
field only.

So I re-wrote the line as...
            ......
# The first of the pipe-delimited fields correspond to the
# sc_order_form_shipping_related_fields.

Even with this small (nit picky) change, I still don't understand
the reference to the 'sc_order_form_shipping_related_fields'.

I also added more comments on the structure of the @sc_shipping_logic
array.


# Breakdown:
#   field 1: shipping type             - i.e. UPS
#   field 2: total price               - order amount shipping relates to
#   field 3: total quantity            - quantity shipping relates to
#   field 4: total measurement         - how much (volume) shipping relates
to
#   field 5: shipping cost/percentage  - Hard value / percentage of total
cost

@sc_shipping_logic = ("ups||1-10||5",     # UPS 1 to 10 items, $5.00 charge
                      "ups||11-||10",     # UPS 11 or more items, $10.00
charge
                      "fedex||1-10||20",  # FedEX 1 to 10 items, $20.00
charge
                      "fedex||11-||30",   # FedEX 11 or more items, $30.00
charge
                      "USmail||1-||5%",   # US Mail, 1 or more items, 5% of
total charge
                      "Pidgeon|15|||10"); # Pidgeon, $15 order, $10.00
charge


After reading the comments on the discount option, I created this...

# Discount logic is the same as shipping logic except
# that whatever value is calculated for the discount will
# be subtracted rather than added to the grand total.
#
# Breakdown:
#   field 1: discount type             - ???
#   field 2: total price of item order - ???
#   field 3: total quantity            - at what quantity does discount
apply
#   field 4: total measurement         - at what measurement does discount
apply
#   field 5: discount ampount          - Hard value or percentage

  @sc_discount_logic  = ("|1-||1");   # no type, 1 or more, $1.00 discount

As you can see, I don't think I understand this very well.

I wish to express my appriciation for the complexity and
sohpistication of this code and the help from this forum.
