Turning off a payment method for a country

Hi,

I have 2 methods of payment set up. Paypal and Nochex.
I need the Nochex option not to show when a customer from a different country other than UK goes through checkout but I just can't get it to work.

I followed these instructions:

**Find "Florida" in the Locations/Taxes Zone Definitions part.

Selected Locations/Taxes Zone Definitions - edited the zone that said "Florida" to read "Great Britain" - then select "Details" and "Edit" - select United Kingdom from the drop-down box, and all zones.

Then go to Payment Modules - select Cheque/Postal Order (obviously I selected Nochex here) - select edit - select Payment Zone - and select Great Britain.**

I also tried putting United Kingdom instead of Great Britain but it still didn't work.
