Hi Kevin thanks for answering, I am using the Areakml.kml file created by Etienne, may I ask if you have an address I can send it to you to have a look, I am happy doing what needs to be done, I just don't know what needs to be done lol.
The short answer is
"I don't know"
I am following the instructions but have got to the point that my meagre knowledge of this is hurting me
