Danny:
No need to apoligize. I have often done such myself. My kids would tell 
me no lectures no math just why is the sky blue?
I , for one have lost a lot of math, in the brain and with the book(most 
lost). So I would certainly like to see the formulae that you have stated, 
but I would like to know what I can use to set up things.
I haave become more like one peson said, "Try it! If it works good, if not 
try agina." But it is nice to be able to use the experteese on this site 
to eliminate most of the "DONT WOIK!".
