in reply to Check user input - reimplementation

kiat,

Your numeric check is pretty weak. I think it should at least allow for a leading '-'. For some ideas for numeric regex checks see perlman: perlfaq4 or do perldoc -q 'is a number' from your command line.

    Thanks YuckFoo!

    In the context I'm using it, it's really just checking for a number - like an id thing that's associated with a name. I'll look up the 'is a number' check to see how I can modify that part.
