PDF with Radio Buttons not able to clear selected buttons or email out a working document

I had a PDF created with radio buttons.  There 10 questions and each question has 10 radio buttons numbered 1-10 for the receiver of the document to select their rating. 

My first issue, is that I selected a few buttons to see if they worked and now I cannot clear those buttons that were selected to send out a clean copy. 

My second issue, is that if the PDF were to go to someone with only Adobe reader then only one or two buttons can be selected.  

I could really use anyones help who actually knows what they are doing with Adobe.

Thanks!!
