ส่งค่า checkbox array ร่วมกับ textbox array แล้วค่าไม่ตรงกัน รบกวนแนะนำหน่อยนะคะ

for ($i=0; $i<count($_POST['checkGE']); $i++)
				{
					if($_POST['checkGE'][$i] != '')
					{
						if($_POST['txtamount'][$i] != '')
						{
							$unit=$_POST['txtamount'][$i];
						}
						else
						{
							$unit='0';
						}							
					$queryE = "insert into  equip_room (equip_id,room_id,amount) values ('".$_POST['checkGE'][$i]."','$room_id','$unit')";
                                        echo $objQuery."<br />";
					$objQuery = mysql_query($queryE) or die(mysql_error());
					}
				}

while($rs = mysql_fetch_array($query)){ 

$num=mysql_num_rows($qrr);
for($i=0;$i<$num;$i++){

<tr>
		 	<td  align="right" valign="middle">อุปกรณ์ภายในห้อง :</td>
    <td>
<?php	
echo "<table border='0'>";
$sql = "SELECT * FROM equipment";
$query = mysql_query($sql);
#$num = mysql_num_rows($qrr);
while($rs = mysql_fetch_array($query)){
    echo "<tr>";
    echo "<td width='28' align='left'>";
    echo "<input type='checkbox' name='checkGE[".$rs['equip_id']."]'  value='".$rs['equip_id']."'>";
    echo "</td>";				
    echo "<td width='130'>";				 
    echo $rs['equip_name'];
    echo "</td>";
    echo "<td>"."จำนวน  <input type='text' name='txtamount[".$rs['equip_id']."]' size='5'> ";
    echo "</td>";
    echo "</tr>";
}
echo "</table>";
?>	
    </td>
</tr>

foreach($_POST["checkGE"] as $key => $value){
    if($value != ''){
        if($_POST['txtamount'][$key] != ''){
            $unit = $_POST['txtamount'][$key];
        }else{
            $unit = '0';
        }							
        $sql = "insert into  equip_room (equip_id,room_id,amount) values ('".$key."','$room_id','$unit')";
	$query = mysql_query($sql);
    }
