@scottcaddy , re post #191...Glad i'm not the only one to focus on missing numbers. Can't get it out of my head until i get an explanation and that uses waaaay too much of my brain's very limited 'RAM'.![]()
Sounds like one of my OCD's....which turns into insomnia going round and round my brain all night long!!![]()
I see that I'm in good company!

Scott
