Possible Duplicate:
PHP: “Notice: Undefined variable” and “Notice: Undefined index”

Hello here is my code:

<?php
        // zmienna $go przekazana metoda GET
      $go = $_GET['go'];

      // sprawdzamy czy zmienna $go nie jest pusta
      if(!empty($go)) {
        // sprawdzamy czy plik o danej nazwie istnieje
        if(is_file("page/$go.php")) include "page/$go.php";
        // jezeli plik nie istnieje wyswietla się komunikat
        else echo "<br />Nie ma takiej strony.";
      }
      // jezeli zmienna $go jest pusta wyswietla się strona glowna
      else include "page/8.php";

    ?>

And I am getting error:

Notice: Undefined index: go in C:\xampp\htdocs\sz\index.php on line 32

The line number 32 is:

$go = $_GET['go'];

Any help? It’s annoying.

     $go = $_GET['go'];
    }else{
     $go = 8;
    }
