### Problems applying shipping costs across different items

Hi,

eCart5

I want to add a £2.95 shipping cost if the sum of all items in the shop is < £12 otherwise shipping is free.

I have set up the following calculation (see attachment)

(([Price]*[Quantity])<12)?(2.95):0

and a shipping rule (see attachment) 'ShippingLessThan12'

My shop at www.belindaclark.co.uk/shop.php shows the item layout - although this live view doesn't have the above rule applied yet - the page is populated from a MySQL database in a repeating group to make adding new products easy. (See attachment for test screenshot)

The problem is that if I choose the same item on the shop page the rule works, adds shipping until cost is £12 or greater the rule works fine, but if I choose different items it adds the shipping cost to each unique item so it appears it's not checking on the subtotal (excluding shipping) to date and just looking at individual item totals.

I've attached

Screenshots of the rules and a test screen with an incorrect total.
eCart_Definition.php
shop.php
comfirm.php

Thanks

Dave

Hi Dave, I think the problem is that you are applying the calculation to the item price and not the cart subtotal.

One of the triggers in the cart object is 'SubTotal for the entire cart contents'

### What do I change

Craig,

I understand what you are saying but how do I check the cart subtotal in the calculation? I note I can see a totalcolumn('totalprice') calculation in the confirm.php page so I know it's there - how do I get it into my calculation?

So i am changing the Calculation from (([Quantity]*[Price])<12)?(2.95):0 to ...?

Dave

Can I use a subtotal variable in the calculation?

Hi Dave,

I can;t check the attachments from the first post, for some reason they don;t always appear for me,

How are you creating the shipping calculation ?

What I would do is open the ecart object, go to the shipping tab, and create a new calculation.

Then my trigger would be

Total number of items > 0 AND SubTotal of items <12

create a flat rate shipping of 2.95

(make sure you put the updated ecart file on the testing server)
