1) for a start your code would be 10 times easier to read if you put it in php tags:

<?php

if (isset($_GET['page']) && isset($_GET['action'])){
$soubor = $_GET['page'];
$action = $_GET['action'];

$soubor2= dirname($_SERVER["SCRIPT_FILENAME"])."/".$soubor."/".$action.".php";
if(file_exists($soubor2)){ 
if(substr_count($soubor,$action,"../")>0){ 
echo "Error";
}elseif($soubor=="index" or $soubor=="/index" or $action=="index" or $action=="/index"){
echo "Error"; 
header("HTTP/1.0 404 Not Found");
}else{

include $soubor2;
}
}else{ 
include "error404.php";
}
}else{ 
include "uvod.php";
}
?>

2) care to tell us what errors you are getting?
