I think you are looking into this problem from the wrong angle.
Create form that shows questions and accepts answers. On that form create custom method GetNextQuestion with code like this

Select Mytable
IF NOT EOF()
   Skip
   Show new question
   create cursor of valid answers
ELSE
   * No more questions, Set property of the form to indicate that
   Thisform.NoMoreQuestions = .T.
ENDIF

and call it from Submit button on your form. This way a user controls the flow of the program. It's very easy to add 'Back' and 'Cancel' buttons to this form.

But how can I allow the user to answer the question before it goes back to the beginning of the scan loop where it will generate an error message?
