Conditional Logic

It would be really useful if we could build conditional logic into the online application forms. Iike I am able to do with my formstack forms: http://www.formstack.com/conditional-logic.html

So for example if an applicant says yes to a question follow up questions could appear.

What might be even better is to integrate your service with formstack: http://www.formstack.com/third-party-integrations.html
