Error setting up different shipping rates

[electroh]

I have added provinces to the UK (Highlands, Northern Ireland, Mainland, etc), and have created different zones for shipping, but I am getting the following error message when exiting the shipping page under business settings.

>>
The following regions have been defined in more than one zone for the same shipping class.
It is recommended that you make appropriate corrections:

For Shipping Class First Class Post, Region United Kingdom is in Zone Northern Ireland and Zone UK Mainland and Zone UK Offshore and Zone Channel Islands and Zone Scottish Highlands
For Shipping Class First Class Post, Region United Kingdom is in Zone UK Offshore and Zone UK Mainland and Zone Northern Ireland and Zone Channel Islands and Zone Scottish Highlands
For Shipping Class First Class Post, Region United Kingdom is in Zone Channel Islands and Zone UK Mainland and Zone Northern Ireland and Zone UK Offshore and Zone Scottish Highlands

What am I doing wrong?

Hi Richard

This will happen if you have a common member country in all the zones. Goto View|Business settings| Shipping and Handling, right click on a particular zone and click on "Properties" you should see the members list on the left.I am guessing you must be having United Kingdom under all these zones.

Cheers
