I have only recently started working with Adobe Acrobat Pro, so my apologizes if this a rather simple question.
I am trying to create fields for telephone numbers. I am aware that in the Format Category there is an option for phone numbers. However, only works for 10 character phone numbers. For people living in other countries, this may be a problem.
What I would like to know is that is there a way to set a field so that only the user can only input certain characters. For this particular field I would like them to be only able to input numbers "0-9", dashes " - ", periods " . " , or Parenthesis " ( ) " . They do not need to be in a particular order.
