While loop radio buttons with different values

I have the following php code that produces some multiple choice questions with each answer per question giving different points.

<?php
$done = $_POST['done'];
if ($done  < '1' )  {
?>
<form action="quiz.php" method="post" />

How many domains do you own? </BR>
<input type="radio" name="op1" value="0"> I don't :( <BR/><input type="radio" name="op1" value="5"> 1 <BR/><input type="radio" name="op1" value="10"> 2 <BR/><input type="radio" name="op1" value="15"> 3 <BR/><input type="radio" name="op1" value="20"> 4 <BR/><input type="radio" name="op1" value="30"> 5 or more <BR><BR>

<input type="radio" name="op2" value="1"> Yes <BR/><input type="radio" name="op2" value="0"> No </BR></BR>

<input type="radio" name="op3" value="1"> less than 5 <BR/><input type="radio" name="op3" value="2"> 5 to 10 <BR/><input type="radio" name="op3" value="3"> 11 to 15 <BR/><input type="radio" name="op3" value="4"> 15 to 30 <BR/><input type="radio" name="op3" value="5"> more than 30  <BR><BR>

 <input type="hidden" name="done" value="1"/>
 <input type="submit" value="Submit...."/>
</form>

<?php
} else {

$score1=$_POST['op1'];
$score2=$_POST['op2'];
$score3=$_POST['op3'];

$total = $score1 + $score2+ $score3;

print "Your score Is " . $total  . "!";
}
?>
</div>

I am trying to modify the code so i can make it work with a database i have.This is the structure of the table question which also includes the answers and the points of each answer.

que_id | test_id | que_desc | ans1 | ans2 | ans3 | ans4 | true_ans | type | points1 | points2 | points3 | points4 |

And this is what i have done so far:

<?php
session_start();
require_once('config.php');

include 'dbconnect.php';

include 'functions.php';
extract($_POST);
extract($_GET);
extract($_SESSION);

if(isset($subid) && isset($testid))
{
$_SESSION[sid]=$subid;
$_SESSION[tid]=$testid;
header("location:$self_page?page=kinder.php");
}
?>

<?php
$rs=mysql_query("select * from question where test_id=20",$conn) or die(mysql_error());
$i=0;
while($row = mysql_fetch_array($rs)) {
$i++;    
$id = $row["id"];
$question = $row["que_desc"];
$opt1 = $row["ans1"];
$opt2 = $row["ans2"];
$opt3 = $row["ans3"];
$opt4 = $row["ans4"];
$score1= $row['points1'];
$score2= $row['points2'];
$score3= $row['points3'];
$score4= $row['points4'];
$answer = $row["true_ans"];

echo "$question<br>";
echo "<input type='radio' id='radio1' name='$i' value='$opt1'/><label for='radio1'>$opt1</label><br>";
echo "<input type='radio' id='radio1' name='$i' value='$opt2'/><label for='radio1'>$opt2</label><br>";
echo "<input type='radio' id='radio1' name='$i' value='$opt3'/><label for='radio1'>$opt3</label><br>";
echo "<input type='radio' id='radio1' name='$i' value='$opt4'/><label for='radio1'>$opt4</label><br>";
echo "<br>";
}

?>

<center>
 <input type="hidden" name="done" value="1"/>
 <input type="submit" value="Submit...."/>
</center>
</form>

<?php
} else {
$total = ...........
}

?>
</div>
</body>

My question is how to pass each answer points using the While loop i have above and how to calculate the total score.
