	// Change 23 to the ID of the form field you want
	$orderID = rgar($entry, '23');
	$user_id = get_current_user_id();

		// switch to mycred_add if you want to add points instead of subtract
		if (function_exists('mycred_subtract')) {

			mycred_subtract(
				'Riduzione punti per invio form',
				$user_id,
				$orderID,
				'Totale Punti: ' . $orderID
