mysql_fetch_array ไม่ออกครับ ผมเป็นพึ่งหัดเขียน php รบกวนด้วยครับ

$sql2 = "select *from order_detail where OrderID='".$_GET['OrderID']."'";
$dbquery2 = mysql_query($sql2) or die(mysql_error());

while($result2 = mysql_fetch_array($dbquery2))
{

		$sql3 = "select * from product where ProductID='".$result2['ProductID']."'";
		$dbquery3 = mysql_db_query($dbname,$sql3) or die(mysql_error());
		$result3 = mysql_fetch_array($dbquery3);
		$Total = $result2['Quantity_oh'] * $result3['Price_sell'];
		$SumTotal = $SumTotal + $Total;
	  ?>
	  <tr>
		<td><?=$result2["ProductID"]."</br>";?></td>
		<td><?=$result3["PName"]."</br>";?></td>
		<td><?=$result3["Price_sell"]."</br>";?></td>
		<td><?=$result2["Quantity_oh"]."</br>";?></td>
		<td><?=number_format($Total,2)."</br>";?></td>
        <td><?=$result2["Bank"]."</br>";?></td>
        <td><?=$result2["AccountNo"]."</br>";?></td>
        <td><?=$result2["Transfer"]."</br>";?></td>

$sql1 = "select * from order_detail where OrderID = '".$_GET['OrderID']."'";
$dbquery1 = mysql_db_query($dbname,$sql1);

while($result1 = mysql_fetch_array($dbquery1))
{
		$sql2 = "select * from product where ProductID='".$resutl1['ProductID']."'";
		$dbquery2 = mysql_db_query($dbname,$sql2) or die(mysql_error());
		$result2 = mysql_fetch_array($dbquery2);
		echo "</br> result2(1) ".$result2['Quantity_oh'];
		$result2['Quantity_oh'] = $result2['Quantity_oh'] - $result1['Quantity_oh'];
		echo "</br> result2(3) ".$result2['Quantity_oh'];
		$sql3 = "Update product set Quantity_oh='".$result2['Quantity_oh']."' where ProductID= '".$result1['ProductID']."'";
		$dbquery3 = mysql_query($sql3);
