Weforms in Drupal 7 different from drupal 6.

Hello,

I was using webforms under drupal 6 to register participants to events. I need to o some processing after the form is submitted. I was using the "confirmation message box" to recuperate the data in the submitted form with the following code:

// e_mail
if(isset($form_values['submitted_tree']['e_mail'])) {
$email = $form_values['submitted_tree']['e_mail'];
}

I saw some info that in drupal 7 the variable $form_values did not exist any longer. But I did not find any pointer to a replacement.

Thanks for your help.
Philippe.
