Thank you all so, so much for the help. Thanks G for the apostrophe lesson, I may well get better grades in my GCSEs now. And thank you to every one else who contributed.
One last question though, Genghis The Engineer, are you the one, or one of a group of people, who started PPRune? Just seems like you have many posts, and, whenever I have a question, you are normally the one who comes out with one of the most informative answers, although everyone does help in their own way
