    That works for what I stated, but not for what I _meant_. It would match 1357, but I would want it to match 1234567. Also, I am looking for a dynamic regex to do this. The whole reason for all this is that I am trying to get a grasp on dynamic regexes (??{}) and thought this would be an easy start.
