Use the second suggestion, or use PHP for the whole thing!
Read out the form answers with PHP, and have the list with correct answers already waiting in the PHP-part on the result page. As said, I'd suggest the use of an array and walk thru it step-by-step, but you could have every correct answer waiting in a separate variable.
Forgive my errors, my php is quite rusty these days.
====
<?
//set counter
$counter = 0;
//set list of correct answers
$correct1 = "A";
$correct2 = "B";
//check if form data is posted
if(isset($_POST))
{
//take out the list of the form, don't forget to sanitize user input!
$answer1 = htmlsafechars($_POST['answer1']);
$answer2 = htmlsafechars($_POST['answer2']);
echo "QUESTION 1<br />";
if($answer1 == $correct1)
{
echo "Your answer of " . $answer1 . " was correct!<br /><br />";
$counter++;
}
else
{
echo "Your answer: " . $answer1 . "<br />";
echo "But the correct answer was: " . $correct1 . "<br /><br />";
}
echo "QUESTION 2<br />";
if($answer2 == $correct2)
{
echo "Your answer of " . $answer2 . " was correct!<br /><br />";
$counter++;
}
else
{
echo "Your answer: " . $answer2 . "<br />";
echo "But the correct answer was: " . $correct2 . "<br /><br />";
}
echo "You scored " . $counter . " correct answers!";
}
?>

I hope this clears the picture a bit, but again, I'd use arrays.
