Rod:
There are LOTS of pieces to the puzzle, not just one or two.
Yep. That is why I post so many questions on the forum.
I see lots of things on the forum where I know 2+2=4, but the experts say the correct answer is 8.
In almost every circumstance the correct formula was 2+2+2+2=8, but I didn't know enough about the complex problem to even be aware of the last two "2s"!
