[Rails] Radio buttons in scaffold

I was trying to create a radio button in scaffold form but got error
here is the form codes-
<%= form_for(@value) do |f| %>
<% if @value.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@value.errors.count, "error") %> prohibited
this value from being saved:</h2>

<ul>
<% @value.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>

<div class="field">
<%= f.label :fname %><br />
<%= f.text_field :fname %>
</div>
<div class="field">
<%= f.label :lname %><br />
<%= form.radio_button :lname, 'yes I have' %> <!-- <label
id="helper.radio"/> -->
<%= form.label :red %>
<%= form.radio_button :lname, 'No I don't' %>
<%= form.label :yellow %>
</div>

<div class="actions">
<%= f.submit %>
</div>
<% end %>
but when I clicked on new button. It's giving me this error-
SyntaxError in Values#new
