Io, try do like this:
You should use $_POST for the security, using $_REQUEST some users can pass a
inject or someting to crash the aplication, and addslashes is for more security
$firstName = addslashes($_POST['firstname']);
if(isset($firstName) && !empty($firstName)) {
$name = $firstName;
} else {
$name = 'Sir or Madam';
}

> if(isset($_REQUEST['firstname']) && !empty($RESULT['firstname'])) {

> } else {
> $name = 'Sir or Madam';
> }

> I also tried adding an underscore to $RESULT (I got the code for this from a
