 Hi Ken McRitchie, I agree with most of your post but not the last comment. At first I thought the same myself but I get the point now. I was looking at the word in its loose meaning but outside of that I would agree this AtG's objection is based on a valid argument.  @AndytheGrump - Thanks for clarifying that, and apologies for calling it 'a bit ridiculous' earlier. I don't think it is but it needs some thought. I hope you continue to input and help us find an appropriate solution. I'm off away from the computer now. Cheers Δ talk  "
