Hi All Again,

I'm not sure whether I should start a new thread or continue this one, so I'll continue this one for now.

All of the suggestions were great, and I now have my technical problem fixed.

I have a larger question, though. I'm trying to put together a program where people can specify variable values and formulas to combine those variables in a configuration file. Using the Math::Expr or Math::Expression modules seems like the best way to go about this to avoid reinventing the wheel. I'd just like to know if there is some other module or framework that people have used that they would consider a best practice for evaluating variables and formulas that are user-provided.

Thanks again for all the help,
Matt
