I've written the next code, but in some way the headers aren't matching the produced posts within the made table,, can someone produce an indication regarding how to improve it?

    <?php

$database =& JFactory::getDBO(); 

//Declare Variables
$user = JFactory::getUser();
$id = $user->get('id');
$name = $user->get('name');

// Display quizzes
echo "</br>";
echo "Quizzes History for : " ;
echo "<b>";
echo $name;
echo "</b>";


echo "</br>";
echo "</br>";

$database->setQuery('SELECT distinct qui.title AS name,' .
        ' ( SELECT GROUP_CONCAT(profiles.title) 
              FROM #__jquarks_users_profiles AS users_profiles
              LEFT JOIN #__jquarks_profiles AS profiles ON users_profiles.profile_id = profiles.id
              WHERE users_profiles.user_id = sessionWho.user_id ) AS profile, ' .
        ' ( SELECT sum(score)  
              FROM #__jquarks_quizzes_answersessions
              WHERE quizsession_id = quizSession.id
              AND status <> -1 ) AS score,' .
        ' ( SELECT count(distinct(question_id))
              FROM #__jquarks_quizzes_answersessions 
              WHERE quizsession_id = quizSession.id ) AS maxScore,' .

            ' ( SELECT count(id)
              FROM #__jquarks_quizzes_answersessions 
              WHERE status=-1
              AND quizsession_id = quizSession.id ) AS evaluate,' .
' quizSession.finished_on,sessionWho.email' .     
        ' FROM #__jquarks_quizsession AS quizSession' .
        ' LEFT JOIN #__jquarks_users_quizzes AS users_quizzes ON users_quizzes.id = quizSession.affected_id' .
        ' LEFT JOIN #__jquarks_quizzes AS qui ON users_quizzes.quiz_id = qui.id' .

' LEFT JOIN #__jquarks_profiles AS profiles ON profiles.id = users_profiles.profile_id '.

' WHERE sessionWho.user_id =' .$id) ;

if (!$database->query()) { //write data and if error occurs alert
    echo "<script> alert('".$database->getErrorMsg()."'); </script>";
}

//var_dump($database);
$tableStyle = "padding: 5px;border:1px"; 
$tdStyle = "padding:5px "; 

echo '<table style="' . $tableStyle . '" cellpadding="7" cellspacing="7">'; 
echo "<tr> <th> Quiz Title </th><th> Score </th><th>Maximum Score </th><th> Unanswered </th> <th>Finished On </th></tr>"; 

$row = $database->loadRowList();
foreach($row as $valuearray)
{
echo '<tr style=" align="center">';
foreach($valuearray as $field)
{

echo "<td>$field</td>";
}
echo "</tr>";
}
echo "</table>";
?>

You've 5 <th> headers but choose 6 posts out of your table. Either clearly print the fields in the table you would like (you need to), or alter the query to simply choose the five you would like.
