When I do that it doesn't get the values for some reason and it gives me a divide by zero error... I think it's because Perl's looking for it's own variables, not the ones set in the shell script. But I can't think of a way to put them in there. The problem with expr is that I can't get to 2 decimal places. I really need that.
