Hi Caveat. Thanks for the link. I've looked it over a couple of times 
and it's good that it has the basic formula. My problem is that while 
I'm very creative/intelligent/determined, it's hard for me to relate a 
lot of mathematical principles to practical problems/solutions in code. 
I don't know if I have a learning disability or some other deficiency, 
but it's always been hard for me to apply abstract principles to things 
in real life, especially mathematics. It's very frustrating as you can 
imagine.

On that note I'm about to start another thread on a similar subject, so 
hopefully someone can help me there too. Fortunately for me most of the 
"crazy" stuff in my app is complete and I can move on to other things.
