Perhaps it’s best if you try, and then if you fail ask the question?
Otherwise you will be asking on the list everytime you need a regular
expression

I recomment the following

  1. Please refrain from bumping your topic so often, you clearly stated
    your request in a previous post, there is no need to repost with no
    added information 10 minutes later. The only thing you might achieve
    is to deter people that may help you.
  2. Most people here don’t mind helping people who are obviously stuck,
    but will mostly ignore those who are blatantly lazy and don’t even
    care to read the links given them.

Is it possible to limit the input upto two digits using regex

  1. Which brings me to the point: Have you even read in full the link
    Simon gave you? There is a box called “Quantifiers”, with which you
    can specify the number of occurrences of a certain pattern in your
    regex. Please go read up on that, or for that matter on any of the top
    results google yields for “ruby regex” or something like that, and if
    you still have problems understanding what is written there, come back
    and ask, if you are just too lazy to make even that little bit of
    research for yourself, then please stay away from this forum, thank you.
