Terry,
I apologise, my intentions were well meant but yes I was a bit blunt. However, getting one over on you was the last thing on my mind after all why would I want to do that, I dont personaly know you and you dont know me, its just an exchange of text on a web site. I wrongly placed you amongst others who post articles on this and other forums who clearly are not Pro's and frankly annoy the hell out of me, they want all the answers but cant be bothered to get the basic foundations. I accept you are not one of these, and I hope there are no hard feelings.
Dave.
