Yes it is answerable but perhaps you might do better if you allow people a bit of time to read and respond.

I'm on a corporate machine at the moment so I can't view your code and therefore can't answer the question at this time.

I would arrange the form slightly differently though. The number of children can vary from zero to n - I would use a repeating content control to allow the user to add extra children as required.
