Asking a question twice owing to a business rule

Question

Hi All,
I have a requirement where I have to ask for the new value of a Number attribute in the same interview as soon I have already answered it depending on a business rule.
e.g. consider the following
The application form is complete if
The applicant's age is known
{The applicant's age is a Number}*(but a hypothetical business rule is: if the age is under 18, ask the question again)*
i.e.
Interview 1:
What is applicant age: *20*
The application form is completeInterview 2:
What is applicant age: *15*
What is applicant age: *13*
The application form is completeInterview 3:
What is applicant age: *12*
What is applicant age: *12*
The application form is completeIs there a suitable workaround.
Hope this helps.
Thanks

Idea 1:+ Use a warning rule like:
Warning("You've stated that your age is under 18.  If this is correct, press the Submit button.") if
the applicant's age < 18
This will cause a warning message to appear on the screen, but (unlike an error event) it will allow the user to continue the interview.
Idea 2:+ Create a second age attribute. If the value of the first age attribute is under 18, ask the second. Of course, this creates a risk of having inconsistent data (like your scenario 2), so you would need additional rules to resolve the inconsistency.
I'd go with the first approach, personally.
