Poll Modification

I am trying to make the poll dynamic based on a variable set in the path of the page.

Here is how I'm passing the variable:http://www.xyz.com/poll/db/test.php?ThePollValue=10&ThePollSize=10

THE PROBLEM:
I get the poll questions, but when I click on "view results" or "vote" I lose the variable value and get the following error: "Poll ID does not exist. "

Here is the code in my php page:

<?php

$string = $_SERVER['QUERY_STRING'] ;
$var = explode("&", $string);
$varA = explode("=", $var[0]);
$ThePollValue = $varA[1];
$ThePollSize = $varA[2];

$ThePollValuePass = strval($ThePollValue);

/* path */
require "./booth.php";

$php_poll = new poll();

$php_poll->set_template_set("plain");
$php_poll->set_max_bar_length($ThePollSize);
echo $php_poll->poll_process($ThePollValuePass);

?>

you need to know the right path that may be is this

/www/poll/db/booth.php
