1)
So this meaning that the way the shipping will be caculated will be based of the additonal information I need to add to the system 
yes
2) Dreamweaver is the only program that will allow you to install and edit eCart using our wizards... otherwise you would have to hand edit with any other editor like notepad.
3) Once you are in the dreamweaver calculations section it will be clear, but yes you will enter it just as you see:
TotalShipping = [shippingprice] * [Quantity]
Did this help? Tips are appreciated...
