    if NaN need help

    maureen27
      have a input text box linked to gotobutton
      If you put in a number and press button it will go to that question.
      Have back and previous buttons that work also.
      Problem is, if someone puts in letters or nothing and hits the gotobutton and then hits the back or previous, I get undefined.

      Can someone please help, if input is empty or alpha is put in box instead of numbers?
