I keep getting this errors Notice: Undefined variable: action in C:\wamp\www\5\adv_mail.php on line 226 Notice: Undefined variable: action in C:\wamp\www\5\adv_mail.php on line 231

any help would be appreciated

    $action is surely undefined. From your code it appears like you expect that to be the HTML hidden field named action that you've defined in your form. That error is simply saying you are trying to run a switch statement on something that doesn't exist. For that you should initialize it first.

    if(isset($_POST['action']))
  $action = $_POST['action'];  // This is missing
else
  die("No action defined");

switch ($action)
{
....
}
