Self-Referential Forms

Say I create a form in InDesign that has a textbox named "Sponsor" and then export it as an interactive PDF.  Is there a way to take that "Sponsor" value (after it was input) and insert it into a paragragh somewhere else in the form, say on blur?  Like if I was creating a photographic release, and someone types their name in the form and then their name appears down in the legalese stuff.
