How to Use the Radio Buttons in Adobe Acrobat

Hello,
I have a question. Is it possible to erase the answers when in "Preview" mode because there is always a box checked when I am in "Preview" but I would like the document to be blank and to be able to deselect as for the multiple choice buttons.
Sorry for my broken English.

Thanks a lot ! I've been doing a few of these for a while but without duplicating, took so long... This is going to save me some precious time. Thanks again !

EXCELLENT video! I've been looking for this information all over the web. Not only is your video dead on, your teaching style is absolutely crystal clear and easy to follow. I'm anxious to see what other Acrobat Pro videos you have. You could save me a TON of time!
