Problema con un form

Salve

ho fatto questo form

<form action="#config.php" method="post">
<fieldset>
<legend>Accedi al database</legend>
<input type="hidden" name="controllo44" value="2">
HOST     : <input type="text" name="valore" value="" size="15" maxlength="20"><br/>
USERNAME : <input type="text" name="valore" value="" size="15" maxlength="20"><br/>
PASSWORD :<input type="text" name="valore" value="" size="15" maxlength="20"><br/>
DATABSE  : <input type="text" name="valore" value="" size="15" maxlength="20"><br/>


<br/>
<input type="reset" value="Cancella"><input type="submit" value="Connetti al db">
</fieldset>
</form>

e questi valori li devo inviare a config.php

e in config.php ho scritto:

$host = $_POST['valore'];
$username = $_POST['valore'];
$password = $_POST['valore'];
$database = $_POST['valore'];

non mi funziona ... perchè?
