Есть таблица:

$table = "<br>";
$table .= "<form class='formular' action='adm_upd.php' method='POST'  enctype='multipart/form-data'>";
$table .= "<div align='center'>";
$table .= "<table width='95%' cellspacing='0' cellpadding='0' border='1'>";
$table .= "<tr>";
$table .= "<td bgcolor='#0099FF' width='35%'><p class='index_text'>Имя</p></td>";
$table .= "<td bgcolor='#0099FF' width='32'><p class='index_text'>ТК1</p></td>";
$table .= "<td bgcolor='#0099FF' width='33'><p class='index_text'>ТК2</p></td>";
$table .= "<td bgcolor='#0099FF' width='33'><p class='index_text'>ТК3</p></td>";
$table .= "<td bgcolor='#0099FF' width='33'><p class='index_text'>ТК4</p></td>";
$table .= "<td bgcolor='#0099FF' width='33'><p class='index_text'>ТК5</p></td>";
$table .= "<td bgcolor='#0099FF' width='33'><p class='index_text'>ТК6</p></td>";
$table .= "<td bgcolor='#0099FF' width='33'><p class='index_text'>ТК7</p></td>";
$table .= "<td bgcolor='#0099FF' width='34'><p class='index_text'>Сумма</p></td>";
$table .= "</tr>";
$table .= "<tr>";
echo $table;
$group_list = mysql_query("SELECT * FROM `users` where `group`=".$_GET['group']."",$db);

//задаю имя формы ТК
$name = 1;
while ($list = mysql_fetch_array($group_list))
{
$table = "<tr>";
$table .= "<td><p class='index_text'>".$list['login']." ".$list['surname']."</p></td>";

$raiting = mysql_query("SELECT * FROM `raiting` where `id`=".$list['id']."",$db);
$tk = mysql_fetch_array($raiting);


$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK1']."></td>";
$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK2']."></td>";
$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK3']."></td>";
$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK4']."></td>";
$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK5']."></td>";
$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK6']."></td>";
$table .= "<td>   <input name='tk".$name."' type='text' size='4' maxlength='4' value=".$tk['TK7']."></td>";
$table .= "<td>   <input name='sum".$name."' type='text' size='4' maxlength='4' value=".$tk['sum']."></td>";
$table .= "</tr>";

echo $table;
$name = $name + 1;
}	 
$table = "</table><br>";
$submit = "<input name='button' type='submit' name='submit' value='Обновить рейтинг'></form>";
echo $table;
echo $submit;

Задача, в любое из полей таблицы ввести обновленное значение, а по нажатию кнопки обновить эту клеточку в базе.

Помогите реализовать уже замучался :(
