ufff... Hello People !. SO !

I need a small QUIZ script for my site . I could not find the right script for me, so I decided to do it myself, BUT I am not a a big php programmer .

So . The quiz is supposed to have 25 questions, with 3 answers each . BUT ! the thing is that some questions can have one, two or three right anwers correct, and all the right answers have to be corect for the hole question to be corect .

So that is my main problem .

The script reads from the database the question number ID, the question, the answers (A1, A2, A3) and the value for each answer. (R1, R2, R3 ) . like for A1 R1=0 , that means R1 is wrong . and so on .

each question has 3 answers .

I CAN NOT get right the code that makes variables for each $_POST and the code that should compare it with the value from the database .

THE CODE

the main page, the quiz page :

                        <form method="POST" action="quiz.php">
                        <p align="left"> Hello what is your name? <br/>
									Enter name:
					<input type="text" name="name" value="Mr./Mrs." size="15" maxlength="15">


<?php

$username="root";
$password="password";
$database="quiz";

mysql_connect(localhost,$username,$password);

mysql_close();

@mysql_select_db($database) or die( "Can not select database!");


function dbQuery($sql, $silence = true)
{
$query = mysql_query($sql);

if(!$query && !$silence)
{
	WriteError('Query Error', mysql_error().'<br />Query String: '.$sql);

	return false;
}

return $query;
}

$query1 = "SELECT Id, ImgFile, Question, AnswerA, AnswerB, AnswerC, R1, R2, R3
FROM `quiz` ORDER BY `Id` ASC 
LIMIT 0 , 26";
$result1 = dbQuery($query1) or die(mysql_error());
$count = 0;
$intrebarecount =0;
$questions_per_row=1;
while (list ($Id, $ImgFile, $Question, $AnswerA, $AnswerB, $AnswerC, $R1, $R2, $R3) = mysql_fetch_row($result1)) 
{ 
	if ($count == $questions_per_row) 
	{ 
		echo '</tr><tr>';
		$count = 0;
	} 

$intrebarecount ++;
echo '
					<td><!-- QUESTION AND ANSWERS CHOICES-->
			<tr>
					<td> _______________________________________ <br/>
							<b>Intrebarea nr.'.$intrebarecount.'</b> <br/>
							<font color=green> '.$Question.' </font> <br/>
							<input type="checkbox" value="'.$R1.'" name="'.$Id.'R1">
							<font color=red>
							'.$AnswerA.'
							<br>
							<input type="checkbox" value="'.$R2.'" name="'.$Id.'R2">
							'.$AnswerB.'
							<br>
							<input type="checkbox" value="'.$R3.'" name="'.$Id.'R3">
							'.$AnswerC.'
							</font> <br/>
					</td>
									<tr>				
					';


	$count++;
}
?>

			<tr>
					<td><br/>
							<p align="center">
									<input type="submit" value="Mark Questions" name="questionsanswer">
									<input type="reset" value="Reset Questions" name="reset">

							</p>
					</td>
			</tr>

THE CODE

the php compare script page, the result page :

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">

$counter = 0;

mysql_connect(localhost,$username,$password);
mysql_close();
@mysql_select_db($database) or die( "Can not select database!");

function dbQuery($sql, $silence = true)
{
$query = mysql_query($sql);
if(!$query && !$silence)
{
	WriteError('Query Error', mysql_error().'<br />Query String: '.$sql);
	return false;
}
return $query;
}

$query22 = "SELECT Id, ImgFile, Question, AnswerA, AnswerB, AnswerC, R1, R2, R3

LIMIT 0 , 26";
$result11 = dbQuery($query22) or die(mysql_error());
$count = 0;
$intrebarecount1 =0;
$questions_per_row=1;
while (list ($Id, $ImgFile, $Question, $AnswerA, $AnswerB, $AnswerC, $R1, $R2, $R3) = mysql_fetch_row($result11))

	if ($count == $questions_per_row) 
	{ 
		echo '</tr><tr>';
		$count = 0;
	} 


$intrebarecount1 ++;

$RR1 = $Id . 'R1';
$RR2 = $Id . 'R2';
$RR3 = $Id . 'R3';

    print $R1;
    print ':::'.$_POST[$RR1];
if (($_POST[$RR1] = $R1) && ($_POST[$RR2] = $R2) && ($_POST[$RR3] = $R3))
{
			$RaspunsFinal = "CORECT";
			$counter++;	
exit;
}
else
{
			$RaspunsFinal = "WRONG";
}


echo '
					<td><!-- ANSWERS-->

    echo '				<br/>
					</td>
									<tr>				
					';

	$count++;
}



			//Generate and out put the result
			$result = $counter / 26 * 100;							

			echo "$counter Questions out of 26 was answered correctly<br/>";
			echo "You got $result % right!<br/>";

			if ($result >= 21)
							{
								echo '<b><big>Congratulations !<br/>';
