ปุจฉา! ถามหน่อยสิ ปกติ พวกท่านๆ ทั้งหลาย มีปัญหามั้ยเกี่ยวกับ การเรียก list box มาจาก db ใน Firefox

<?php
<select name="vender" class="TXT-GRAY" id="vender">
<option>---------- กรุณาเลือก ----------</option>
<?
$sql = "Select * from vender order by vender_id asc ";
$result= mysql_query($sql);
while($row= mysql_fetch_array($result))
{ echo "<option ";
if($row["vender_id"]=="$vender_id"){ echo " SELECTED "; }
echo "<option value='{$row["vender_id"]}'>{$row["vender_nm"]} </option>"; }
?>
</select>
?>

ผิดป่าวครับ

<?php
{ echo "<option ";
?>

<?php
{

<?php
<select name="vender" class="TXT-GRAY" id="vender">
<option>---------- กรุณาเลือก ----------</option>
<?
$sql = "Select * from vender order by vender_id asc ";
$result= mysql_query($sql);
while($row= mysql_fetch_array($result))
{
echo "<option value=\"".$row['vender_id']."\"";
if($row["vender_id"] == $row["vender_nm"] ){ echo " selected=\"selected\""; }
echo ">".$row['vender_nm']."</option>\n"; }
?>
</select>
