I need to set up zones (regions within the UK) for shipping purposes. When I use the zones shipping module I get a blank screen when I go to checkout so I presume I've set something up incorrectly.

I have set up 3 zones within the UK and defined the sub-zones but the problem persists.

Other shipping modules work OK but are not what I need.

Any help would be appreciated.
