UK advertiser, wants to prevent ads being shown in Ireland / Eire.

Is there a way to prevent my ads being shown in Ireland / Eire

[sunroomguy]

I am a UK Advertiser with Yahoo Search Marketing (Overture Pay Per Click). Is there a way to prevent my ads being shown in Ireland / Eire?

Maybe this is easy to so - and I assume it is possible - but I am darned if I can work out how to do it on their interface. Maybe if i set up the campaigns again it gives me the option to exclude Eire?

At present I get enquiries from Eire, that due to the nature of what we do, I cannot do anything with. I appreciate N Ireland is part of the Uk, and I could live with it being displayed there, but I am wasting my money having the ads shown in Eire.

Any pointers gratefully received
