how to apply document rights to pdf files?

Question

I had to create a form , which I did in indesign and saved as a pdf. It now needs to be interactive in the sense that I had to create fill-in areas( for the qty and price slots). I did this in adobe pro 7 but the problem is that clients can fill in the slots but they cant save it. I need the file to be like this: http://www.irs.gov/pub/irs-pdf/fw9.pdf
I noticed it said : this form has document rights applied to it. These rights allow anyone completing the form, with the free Adobe Reader to save their filled-in form locally.

HELP ME DO THIS PLEASE

Q. Can I save Adobe PDF forms in Adobe Reader after I have filled out a PDF form?
A. Yes, provided your form has had the "local save" capability turned on with Adobe LiveCycle Reader Extensions. Team members both inside and outside an organization have access to and can interact with forms. You can easily open, fill out and submit PDF forms, even from handheld devices and over wireless connections. However, if the "local save" capability has not been activated in your PDF form, you will not be able to save the form data with Adobe Reader.

You need to acquire Adobe® LiveCycle® Reader® Extensions. Sorry, I have no idea of the cost. http://www.adobe.com/products/server/readerextensions/
