Thanks! I will look over your code and see if I can use it.

The thing about this particular project is that the company I work for is worried that the guy who wrote it might quit...and then there is no one who knows anything about it at all :) Nice, right? Bur the author didn't think anyone would have to read the code, so there are no comments, and all the variable names are $a and $b. :)

Thanks for your help!
