		$vis = $_GET['vis'];
		if (isset($vis)) {
			$cs = explode("/", $vis);
			if (!empty($cs[1])) { 
				$include = str_replace("/", "", $vis);
			} else { $include = "$vis.php"; }
		}
		if (!file_exists($include)) { $include = "missing.php"; }
		require_once($include);

	?>

 

Notice: Undefined index: vis in /web/sirkulus/beta/index.php on line 56

It is the $_GET you have to check for isset as that is the array with the "unknown" index.
