Sweet!  That seems to work...  What is the "^\d+$" doing exactly?  I've
done a few searches and didn't come up with anything...  where would its
use be documented?

It is a regular expression where
  ^
means the start of the string,
  \d
means a decimal digit
  \d+
means one or more digits and
  $
means the end of the string.
