Flexi Auth issue with CSRF Proetection

Hi,
I am trying to implement the flexi auth library in my projcet but i am facing one issue, when i enabled the CSRF Protection the token name is coming but hash value is not coming . For re-check i also enable CSRF protection in demo provided on "http://haseydesign.com/flexi-auth/" but same issue i faced there.
If any one have answer on this please reply me.
thanks    

try something like this

<input type="hidden" name="<?php echo $this->security->get_csrf_token_name(); ?>" value="<?php echo $this->security->get_csrf_hash(); ?>">

thanks, issue was resolved
