Clearing form fields in a PDF

I am using Microtype's TimeSavers and SP Form assistant to create forms and calculators in my FrameMaker documents. Is there a way to add an extendscript that will reset/clear the fields when the PDF is opened each time? It is going to be part of a book PDF on a server, so it's going to be accessed by many people. I need any fields to be cleared/reset on open so that each time it will be cleared for the person opening the PDF.

Thanks, Gary
