Indesign Form Fields and Text Variables

[Maisy1]

I want to create a form , but have elements of my document that are text variables (running headers, export dates, page numbers etc). If I create a form as a PDF will these elements still work? 

[Mike Witherell]

Will they appear? Yes. What do you mean by "work"?

Export as Interactive PDF and you will know.
