I\'m borrowing/adapting this simple html/javascript form set up to put some data in the database. The original code uses text fields in the form, but I\'m using radio button
No, an Id attribute should always be unique. If you're using jQuery (looks like you are), you can select it with $('input[name=interview]');.
$('input[name=interview]');
Instead of id="nick"
id="nick"
You can use name="nick"
name="nick"
Or
class="nick"
