PHP Not Displaying Data

Can someone else eyeball this code to see if you can tell me why it is not displaying the mysql data in a browser?
<?php
$host="localhost"; // Host name 
$username="user"; // Mysql username 
$password="password"; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="test_mysql"; // Table name 

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);
?>
<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="400" border="1" cellspacing="0" cellpadding="3">
<tr>
<td colspan="4"><strong>List data from mysql </strong> </td>
</tr>

<tr>
<td align="center"><strong>Name</strong></td>
<td align="center"><strong>Lastname</strong></td>
<td align="center"><strong>Email</strong></td>
<td align="center"><strong>Update</strong></td>
</tr>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td><? echo $rows['name']; ?></td>
<td><? echo $rows['lastname']; ?></td>
<td><? echo $rows['email']; ?></td>

// link to update.php and send value of id 
<td align="center"><a href="update.php?id=<? echo $rows['id']; ?>">update</a></td>
</tr>
<?php
}
?>
</table>
</td>
</tr>
</table>
<?php
mysql_close();
?>

Add error_reporting(E_ALL) to the top of the script.

Line 13 change to
$result=mysql_query($sql) or die( mysql_error() );

Line 30 change to
while($rows = mysql_fetch_assoc($result)){

Lines 33-35 change to
<td><?php echo $rows['name']; ?></td>
<td><?php echo $rows['lastname']; ?></td>
<td><?php echo $rows['email']; ?></td>

Remove extraneous lines 47-49

I assume you are not seeing any errors,  and make sure you have data on the table ;)

On another note, you have a // comment in the in the HTML

<?php

ini_set('display_errors', 1);
error_reporting(E_ALL^E_NOTICE);

?>

Place this code in the top of the script, this will show up the actual error in the script, later you can disable this code.

Hope this helps

Please add this code at the top of you page and check
ini_set('error_reporting',E_ALL);
ini_set('display_startup_errors','On');
ini_set('display_errors','On');

srry instead or row it should be print_r(rows);
To check whether the data is actually present in table or not
