try:
if (isset($_GET['msg']) && !empty($_GET['msg'])) {
$param = $_GET['msg'];
//do whatever
}
As an aside you should also be urlencoding the query string values:
home.php?msg=selected+records+have+been+deleted+etc
not
home.php?msg=selected records have been deleted from the database.
(see: http://uk2.php.net/urlencode )
