anything wrong in this calculation?

Anything wrong with the calulation below? it used to work for me and now all of the sudden it doesnt work. The average still works but the calc before does not.

<?php
// Vars! //
require './include.php';
$Score = 0;
// End of Vars! //
/**
* ***********COOKIE STUFF!**************
* What this will do is first check to see
* if there is a cookie that has data in
* it. Next if there is no cookie we then
* calc the score and enter that data into
* the cookie.
*/
$i = unserialize($_COOKIE['Quest']); //Unserialize the data in the cookie (if there is one) and put the array in the var "$i"
if ($i[TotalScore]) { // If there is a data from the cooke do this...
$TotalScore = $i[TotalScore]; //Put data from the score in the cookie
$CookieData = serialize(array ("QuizID" => $QuizID, "Taken" => "Yes", "TotalScore" => $TotalScore)); //Load up the data!
setcookie("Quest", $CookieData, time() + 60 * 60 * 24 * 30); //Bake the cookie!
} else {
// This will clac the score..
foreach($Quiz as $Question) {
// This is a quite verison of the answer checker as show above...
$QuestionArray++;
$Var = "Q" . $QuestionArray;
// This var is for the ammount of questions this will be used to calc the grade
$QuestionAmt = $QuestionAmt + 1;
if (stripslashes($$Var) == stripslashes($Quiz[$QuestionArray]['Answer'])) {
$Score = $Score + 1;
}
}
$TotalScore = round($Score / $QuestionAmt * 100); // Calc the score and round it
$CookieData = serialize(array ("QuizID" => $QuizID, "Taken" => "Yes", "TotalScore" => $TotalScore)); //Cookie data
setcookie("Quest", $CookieData, time() + 60 * 60 * 24 * 30); //Bake it!
}
// Clear dem vars!
$Question = "";
$Var = "";
$QuestionArray = "";
$QuestionAmt = "";
