Thankyou Robert for taking the time to do all of this for me. You must be a very intelligent and kind and understanding person. I have only skipped through what you've put so far as I'm felling really bad at the moment, mornings always seem to be very bad for me. But I promise as soon as I feel a bit better I will read it again and the web-sites. Sorry, can't do it now but I wouldn't take any of it in in this state. Again I thank you for going to all this trouble and when I've read it probably I'll send you a proper answer and maybe some questions, if thats ok. What a great guy. Love Tracy x
