Customizing the shipping rate

I need to have a shipping rate based on the subtotal of all products in the cart that equals a minimum of $4 or 10% whichever is higher. I entered the following code in the eCart Object calculations, but it calculates on each line item rather than the subtotal.

For example, if I have three items at $15 my subtotal is $45 and shipping should be $4.50. I now get shipping at $12.00 or $4 for each item based on item totals rather than the subtotal of all items.

Here's my current code: ((([Price] * [Quantity]) * 0.10) > 4)?(([Price] * [Quantity]) * 0.10):4 How do I adjust this to get what I'm looking for?

don't do this on the calculation tab, as you have discovered, calculations are applied on a line item basis.

Instead, do this on the shipping tab.

Create a new shipping rule:

trigger:
based on number of unique items in the cart > 0

calcualtion:
Flat Rate calculation of:
(($this->TotalColumn('TotalPrice') * 0.1) > 4)?$this->TotalColumn('TotalPrice') * 0.1:4

Jason,

Got the first part. But have a question here:

calcualtion:

Flat Rate calculation of:
(($this->TotalColumn('TotalPrice') * 0.1) > 4)?$this->TotalColumn('TotalPrice') * 0.1:4

I don't see a place after Flat rate selection in the shipping tab to insert the calculation code.

Does this go in the calculation tab and if so what goes in the calculation section of the shipping tab?

when you select flat rate, there is a text box to enter the flat rate:
Create a Flt rate Shipping of $[text box]

enter that code in the text box
Create a Flt rate Shipping of $[(($this->TotalColumn('TotalPrice') * 0.1) > 4)?$this->TotalColumn('TotalPrice') * 0.1:4]

(Without the square brackets, I am using them to illustrate the text box)

Jason,

Everything is working. Many Thanks
