erreur

j'ai mis:
<?
$actu = $_COOKIE['actu'];
IF ($_COOKIE['mini-chat']=="on")
{
include "minichat.php?actu=$actu";
}
ELSEIF ($_COOKIE['mini-chat']=="off")
{
include "tables_off.php";
}
ELSE
{
include "minichat.php?actu=$actu";
}
?>[/color]

et il me répond:

Warning: main(minichat.php?actu=60): failed to open stream: No such file or directory in /var/www/free.fr/a/4/tipaldi/CJTV/CJTV00.php on line 474
