$PHP_SELF Problem

Hey there,

i've got the following problem. on my index.php i want to include the cutenews. the cutenews is in the folder /news

My index.php looks like the following:

<?
switch($_GET['action']){
case "news": include("news.php"); break;
default: include("news.php"); break;
}
?>

the news.php in the root includes:

<?PHP
 $number = "4";
 $category = "1,2";
$QUERY_STRING = 'action=news';
 include("news/show_news.php");
?>

how do i have to edit the news.php when i'll use $PHP_SELF = 'X.php'; or $QUERY_STRING = 'X'; ???

thanks a lot for your help!
