[ic] Multiple shipping addresses - Please help!

[Interchange user]

Hello,

I still need someone to shine some light on the multiple shipping addresses 
feature implemented in the Foundation demo. Back on the 15th, I wrote:

>From what I can see, shipping charges are not increased accordingly if 
someone uses multiple addresses per order, and the other problem is allowing 
people to type in their country when adding or editing an address, rather 
than selecting it from a drop-down list (I am calculating shipping by 
country).

I would prefer to simplify things anyway, and just have one shipping address 
per order. It would be good to support saved shipping addresses though, and 
have the customer select the required address on the checkout page (like 
Amazon).

Does anyone have any examples, or can someone point me to the relevant 
documentation? I couldn't find any reference to the [address], [modifier], 
mv_ip, mv_an, etc. tags / form variables from the 'cart' component.

Also, where is the code behind the ship_addresses.html page? I couldn't find 
any reference to the [table-editor] tag. What does the 'Save here only' 
checkbox do?

Thank you.

I've tried chopping bits of code out from the 'cart' component and putting it 
in the checkout page, to no avail. Again, I just want to allow the customer 
to select previously saved addresses on the checkout page, and get rid of all 
that stuff on the basket page. I can't find any documentation on [address], 
{address_book}, or any of the other stuff in there.

I'd really appreciate any help; I seem to spend almost all of my time trying 
to figure out Interchange, rather than getting any work done, and it's 
driving me nuts!

Thanks.
