How to get submitted values on $formstate['values'] instead of $formstate['input']?
If you want to get $formstate['values'] or $form_state['input'] values .You have to write like below.

    function create_entry_form($form, &amp;$form_state){
        $form['entry']['password'] = array(
          '#type' =&gt; 'password',
          '#required' =&gt; TRUE,
          '#default_value' =&gt; '',
          '#maxlength' =&gt; 15,
        );

        $form['entry']['submit'] = array(
          '#type' =&gt; 'submit',
          '#value' =&gt; t('OK'),
          '#weight' =&gt; 100,
        );
        $form['entry']['emailid'] = array(
          '#type' =&gt; 'textfield',
          '#required' =&gt; TRUE,
          '#default_value' =&gt; '',
          '#maxlength' =&gt; 25,
        );

        $form['entry']['reqbtn'] = array(
          '#type' =&gt; 'submit',
          '#value' =&gt; t('Request'),
          '#weight' =&gt; 106,
          '#submit' =&gt; array('request_site_password'),
          );



      return $form;  
    }
   function request_site_password(&amp;$form, &amp;$form_state) {
    drupal_set_message('&lt;pre&gt;' . print_r($form_state['input'], TRUE) . '&lt;/pre&gt;');
  }


You missed '&amp;$form' in this function request_site_password(&amp;$form, &amp;$form_state)
