Additional Fields to Shipping

**Zencart Version:**v1.3.9h

Hi, first time poster here. I only just started looking at zencart last week and i've actually found it amazing for a lot of stuff. Even convinced my current client that choosing this is MUCH better over template based shopping servers... god knows what he was thinking doing that.

Butyeah, to the problem at hand... my client mentioned above is running a reptile store. As such he needs two problems worked out.

1 - An additional field (tickbox) in order to choose whether you want a carraige or not WITH the shipping

2 - *A way to seperate the shipping costs of frozen stock and apparatus, and make it so that they can be ordered together. *

I keep running into a brick wall with this, and i'm not sure where to go. Every time i've had trouble i've googled, and this place has turned up so i figured i'd ask you knowledgable folk.

Any help is really appreciated. Cheers.
Dan.

Sorry for the double post, it wouldn't allow me to edit.

The details i was given.

Livefood on its own £4.95
Frozen on its own £8.99 (up to 4kg)

Livestock must be billed separately regardless of if wanting other goods £18.50
Standard delivery for everything else including livefoods (not frozen or livestock) £8.95

You know what? Forget it. I worked it out on my own. Such a brilliant community you have here.
