Word form - need help with code for text colors and popups

I have a word form that I have put into SECTIONS. Depending on which radio buttion is selected allows the user only to enter in the appropriate sections. I would like the sections that are protected (true) to be in a light grey text.

I would also like to have a popup when the form is opend with the radio buttions on it. I want the usere to select the radio buttion before they can edit anything on the page.

Please see attached for Code.
