# [Plugin: WP-reCAPTCHA] Undefined variable errors

 * I just installed the recaptcha plugin and I’m getting some warnings ahead of 
   the captcha widget which is showing up:
 * `Notice: Undefined variable: needed_capability in /...../public/blog/wp-content/
   plugins/wp-recaptcha/wp-recaptcha.php on line 438`
 * `Notice: Undefined index: rerror in /....../public/blog/wp-content/plugins/wp-
   recaptcha/wp-recaptcha.php on line 443`
 * `Notice: Undefined index: rerror in /...../public/blog/wp-content/plugins/wp-
   recaptcha/wp-recaptcha.php on line 494`
 * I looked at the code and on line 430 of the ‘wp-recaptch.php’ file is the following:
 *     ```
       function recaptcha_comment_form() {
          global $user_ID, $recaptcha_opt;
   
          // set the minimum capability needed to skip the captcha if there is one
          if ($recaptcha_opt['re_bypass'] && $recaptcha_opt['re_bypasslevel'])
             $needed_capability = $recaptcha_opt['re_bypasslevel'];
   
       	// skip the reCAPTCHA display if the minimum capability is met
       	if (($needed_capability && current_user_can($needed_capability)) || !$recaptcha_opt['re_comments'])
       		return;
       ```
   
 * It appears that the variable $needed_capability is not being set up because $
   recaptcha_opt[‘re_bypass’] is not TRUE. It is actually NULL. $recaptcha_opt[‘
   re_bypasslevel’] is set to ‘read’. It appears to me that if $recaptcha_opt[‘re_bypass’]
   is NULL then $needed_capability is never set although it is tested in the following
   line (438).
 * Is there a default $needed_capability set somewhere that is not being picked 
   up? Thanks for any help!
