Hi there jas244510:, I hope you'll trouble yourself to review our Forum Rules{click}.  You already accepted the rules when you signed up for our forum, and you have to follow them, whether you agree with them or not, or even if you're unaware of them.

You want it step by step, which is the same thing as saying for us to do it all for you.  We don't do that here.  Have you recently been taught a formula that relates the information you have?
