Shipping Rate Calculations

eCart5

I'm about to work with checkout wizard. I have all the info for my gateway, etc, but in our business we charge for shipping at 10 percent of the total before taxes with a $4.00 dollar minimum.

My question is how I go about setting up calculation code to do what I need done? More specifically what do I do in the checkout wizard re: shipping and what do I do in eCart Object to set up the calculations, or am I missing anything else?

in the eCart object, create a new calculation, name it "shipRate" as:
((([Price] * [Quantity]) * 0.10) > 4)?(([Price] * [Quantity]) * 0.10):4


this basically says
If the TotalPrice times %10 is greater than 4, use TotalPrice times %10. If not, use 4

Then on the shipping tab, create a new shipping rule. Set the trigger to Total Number of Unique Items in the cart ">" "0"


and set the calculation to use "Based on column subtotal"
Subtotal of column "shipRate" "plus" "0"

Jason,

Thanks for the response. I'm about four hours away from putting it into action. Just have a couple of things left to do to complete my cart set up. I'll let you know how everything goes.
