Hi List This is just to let you know that with help from Tim Burgess and George Bell, they, rather than I, have managed to resolve the problems that I had and explained to you on this list 24 hours ago. It would be good therefore to close this particular thread. My thanks go out to all those who have helped me over the past two weeks.
