[plugin: Contact Form 7 ] Runnign function before and after

Hi,
i’ll try to execute a couple of functions before and after sending mail.

The functions “before” is ok but i’m not able to run the function after mail sent.

My code inside the function.php file

add_action( 'wpcf7_before_send_mail', 'FunctionsBefore');
	function FunctionsBefore($contact_form) {
	 $idForm = $contact_form->id;
	 ...
}

add_action( 'wpcf7_mail_sent', 'FunctionsAfter' );
function FunctionsAfter($contact_form) {
    	$idForm = $contact_form->id;
        ...
}

Debugging i see that when i’m at line add_action( ‘wpcf7_mail_sent’, ‘FunctionsAfter’ ); the $contact_form var is no more defined.

Where is my mistake?

Thank’s a lot and sorry for my english.
