Just finished it. Really good -not perfect but good. There was about 5 hard sticking points for me and if you need help getting through and Mark is busy and not available, I can help. But as he does not post the answers on this board, and it's for a good reason, to keep it a good puzzle, I won't either. I will respond to email though, but please ask soon as my memory is not all that great. It is a good mod and worth finishing. I nearly quit more then a few times. Mark was good help and my thanks to him. This one is tougher then the others but well done. Good luck and don't give up!-Rob--Robspace1@msn.com
