You're joking right??? This is a simple problem in high school level mathematics. I won't answer it, but I'll give a hint: Geometric Series. Enough said???? I wouldn't expect John Doe off the street to know this, but the fact that someone where you work does not know high school math is scary. -- Bob Silverman #include <std.disclaimer> Mitre Corporation, Bedford, MA 01730 "You can lead a horse's ass to knowledge, but you can't make him think"
