I have this code here:

```
<?php   
$search=htmlspecialchars($_GET['load']); 
$method = isset( $_GET['btnAction'] ) ? $_GET['btnAction'] : '';

switch( $method ) {
    case 'Search':
      header('Location: search.php?load=$search');
        break;
    case 'Im Feeling Lucky':
        //do chapter two stuff
      header('Location: search_lucky.php?load=$search');
        break;
    default:
        echo 'Not a valid operation';
}

?> 

```

Everything works except the $search variable, I don't understand what is wrong.

Can someone tell me why $search variable dont work when i hit this url: `handler.php?load=keyword&btnAction=Search`
