So I have this code inside my lib/ folder:

class GlobalConfig::SetHelper
  def self.yes_no_input(configuration)
    value = configuration.value
    name = configuration.name
    "#{radio_button_tag name, true, (value == true), {:id => "#{name}_yes"}} #{label_tag "#{name}_yes", 'yes'}
     #{radio_button_tag name, false, (value.blank? or value == false), {:id => "#{name}_no"}} #{label_tag "#{name}_no", 'no'}"
  end
end

But it returned: undefined method `radio_button_tag' for GlobalConfig::SetHelper:Class when I run the code.

How do I fix this. Anyone?

Thanks
