body: <p>I have the following bit of haml code</p>
  
  <pre><code>%section.form
    %form.standard{action: registration_index_path, method: 'get'}
      %fieldset{"aria-labelledby" =&gt; "content-header"}
        %legend 
        %ul
          %li
            %label{for: "Associate-id"} Associate Id
            %input#Associate-id{name: "id", size: "80", type: "text", value: current_user.associate_username}/
          %li
            %label{for: "email"} Email
            %input#email{name: "email", size: "80", type: "text", value: current_user.display_name}/
          %li
            %label{for: "reason"} Reason for Access
            %textarea#reason{cols: "200", name: "description", value: ""} 
          %li
            %label What type of access would you require?
          - Role::ROLES.each do |role| 
            %input#roles{name: "access", type: "checkbox"}/
            %label{for: "roles"} #{role} 
      %fieldset.input-actions
        %legend Actions
        %input.primary-action{name: "invoke", type: "submit", value: "Send"}/
        %input.cancel{name: "invoke", type: "submit", value: "Cancel"}/
  </code></pre>
  
  <p>Here params[:access] only gives me if its on or not . How do i actually get the values of the selected checkbox ? .
  thank you.</p>
