Code Injection to Hide/Show form fields on radio button selection

Hoping someone can help. My form starts with a question with radio button yes/no options. I have the rest of the form hidden. I want the other fields to show based on "yes" selected, and an alternate message to show based on "no". Hiding the fields works just fine, but cannot get it to show the other fields or alternate message when an option is selected. Simply does not respond.

Update; Not sure if it matters, but I have two forms on my site.
