I'm not sure I understand what to put in eCart object to calculate the shipping the way I want it to. I have 8 items in two columns for a total of 16 items. One column is called DVDID and the other CDID. I need to tell the shipping that if any items in the cart from either of those columns is 2 or less, the price for shipping is this much. If the items from any of those two has a quantity of 3, then it's this much, if 4, this much etc. all the way to 10. Anything above 10 is equal to this much x 1% of the total. How to do that?
