สร้าง link จาก database ด้านซ้ายได้ แต่ด้านขวาไม่รับค่าตัวแปรเพื่อดึงข้อมูลมาแสดงผล ใครพอจะช่วยได้มั๊ยครับ

<div id="content">
<?
$link = mysql_connect ("localhost","ownmylif_db","1234");
if (!$link)
{
	print ("Error");
	exit ();
}
mysql_select_db("ownmylif_db", $link);
?>
<table width="100%" border="1" cellpadding="4">
<tr valign="top">
<td width="30%">
<?
$sql="select id, thainame from nutritionalmedicine";
$res=mysql_query ($sql, $link);
while($row=mysql_fetch_row($res))
{
print ("<a href=nutritionalmedicine.php?ID=$row[0]> $row[0] $row[1] </a><br />"); 
}
?>
</td>

<td width="70%">
<?
print ("$ID");
if ($ID <> null)
{
$sql="select * from nutritionalmedicine where id=$ID";
$res=mysql_query($sql ,$link);
if (mysql_num_rows($res)!=0)
	{
	$row=mysql_fetch_row($res);
	print ("id:$row[0]<br />");
	print ("thai name:$row[1]<br />");
	print ("eng name:$row[2]<br />");
	print ("other name:$row[3]<br />");
	print ("pic1:$row[4]<br />");
	print ("pic2:$row[5]<br />");
	print ("pic3:$row[6]<br />");
	print ("about:$row[7]<br />");
	print ("diet:$row[8]<br />");
	print ("homeremedies:$row[9]<br />");
	print ("dailysupplements:$row[10]<br />");
	print ("herbaltherapy:$row[11]<br />");
	print ("exercise:$row[12]<br />");
	print ("acupressure:$row[13]<br />");
	print ("avoid:$row[14]<br />");
	}
else
print("No Data");
}

<?
