Cant save score as i dont use index.php

Hey

When ever it tryed to save a score it goes
/index.php?act=Arcade&do=newscore

index.php is my wordpress
forums.php is my VB forum

i edited the url and added the forums.php and it tryed to save ok
but this is only when i edited the url after it failed to save

So how can i get it to point to forums.php all the time?

Thanks

Edit np fixed it

Add this to my wordpress index.php

PHP Code:

// ibProArcade 
if($_POST['module'] == "pnFlashGames") 
{ 
    require_once('./global.php'); 

    switch($_POST['func']) 
    { 
        case "storeScore": 
        $_GET['act'] = "Arcade"; 
        $_GET['module'] = "arcade"; 
        $_GET['do'] = "pnFStoreScore"; 
        break; 

        case "saveGame": 
        $_GET['do'] = "pnFSaveGame"; 
        break; 

        case "loadGame": 
        $_GET['do'] = "pnFLoadGame"; 
        break; 

        case "loadGameScores": 
        $gid = $vbulletin->input->clean_gpc('p', 'gid', TYPE_INT); 
        $uid= $vbulletin->userinfo['userid']; 
        $game = $db->query_first("SELECT * FROM " . TABLE_PREFIX . "games_scores WHERE mid=$uid AND gid = $gid ORDER BY score DESC LIMIT 0,1");
        $scores = $game[score]; 

        if($scores != false) 
        { 
            //Return true 
            print "&opSuccess=true&gameScores=$scores&endvar=1"; //send endvar to keep opSuccess separate from all other output from PostNuke
        } 
        else 
        { 
            print "&opSuccess=false&error=Error&endvar=1"; 
        } 
        break; 
    } 
} 

$act = $_GET[act]; 
$autocom = $_GET[autocom]; 
$showuser= $_GET[showuser]; 
if($act == "Arcade" || $autocom=="arcade") { 
include "arcade.php"; 
exit(); 
} 
if(!empty($showuser) && $showuser >= 1) { 
$u = $showuser; 
$_GET[u] = $showuser; 
include "member.php"; 
exit(); 
}
