Captcha on widget

I added the captcha plugin and in the mailpress/mp-includes/class/MP_Widget.class.php file, I added :

if(function_exists('cptch_display_captcha_custom')){ echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom(); }
if(function_exists('cptch_check_custom_form') && cptch_check_custom_form() !== true){ echo "<br/>Veuillez compl&eacute;ter le CAPTCHA.<br/>"; }
echo '<input class="MailPressFormSubmit mp_submit" type="submit" name="MailPress_submit" value="'.esc_attr($options['txtbutton']).'" />';

But it’s doesn’t work…

Thanks for your help
