I follow the article in Internet ,

1.check the config.xml

<global>
   <blocks>
      <customerlogin>
         <class>CustomerParadigm_Customerlogin_Block</class>
      </customerlogin>
   </blocks>
   <helpers>
      <customerParadigm_customerlogin>
         <class>CustomerParadigm_Customerlogin_Helper</class>
      </customerParadigm_customerlogin>
   </helpers>

it is ok
