Just one of those times when I just can't see the problem. It appears to be the opening brace at the end of the if statement.

  $('#title_number').change(function () {
    if ($('#title_number').val() == 73) or ($('#title_number').val() == 74) {
    $('#ProfessorDiv').show();
    }
  });

    There is no or keyword in JavaScript, and the entire expression used by the if must be in (). Commented Jul 30, 2013 at 3:26

Your if statement is malformed (parenthesis grouped or, not the entire expression):

if ($('#title_number').val() == 73 || $('#title_number').val() == 74) {
  $('#ProfessorDiv').show();
}

Also there is no such logical operator as or. You meant ||.
