Glad that was useful, Threegees. You were very kind about the help I give on here - but I'm quite happy to be given help too. There are some very smart people on the Forum, I've been rescued a lot in the past. I help out only on the puzzles I've been doing for decades, the ones I can manage. I know my limits - you'll seldom see me helping out with the Listener or the Times Club Monthly Puzzle!
