Quite frankly, I don't understand how this:

Code:

F = G * ( 1 / N - N / (1 + I)^N - 1 )

works at all, when *CLEARLY* the formula starts with 1/I and *NOT* 1/N.

Also, you are missing the *REQUIRED* parentheses around the sub-expression ( (1+I)^N - 1)

I think the only reason it *SEEMED* to work was because you used the *SAME NUMBER* (10) for both I and N!!!

PURE LUCK!
