We can calculate the return on investment with no problem. What we want to
do is make the rate compound quarterly, rather than annualy. Is there a way
to do that?

We calculate a $15,000 investment on 1/1/02 worth $25,794 on September 30,
2006, as a 14.95% rate of return. But if we use another program and
compound out quarterly, the return is only about 12%.
