I wantt to make a calculator with excel. I know some excel basics, but
I need help with the formula in the link below.

Again I need help with the formulas. I could use these but I need them
offline also. This is where excel comes in.

I know how to ste the name fields and have an area for the value to be
entered, the formula is killing me.

Thanks
