HELP!!

[archonis]

I have tried every format I could think of, I still get this stupid error when I use the same line in other pages.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''inbox' SET delete = '1' WHERE mailID = '218'' at line 1

Here is the code i wrote.

<?
ini_set("session.cookie_domain"," .mytowndate.com");
session_start(); 

$myusername = $_SESSION['username']; 

$mailID1 = $_GET["mailID"];



$host="localhost"; // Host name 
$dbusername="********"; // Mysql username 
$dbpassword="********"; // Mysql password 
$db_name="trevors4_MTD"; // Database name 
$tbl_name="inbox"; // Table name 

// Connect to server and select databse.
mysql_connect("$host", "$dbusername", "$dbpassword")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");



$a = "1";	 
$sql = "UPDATE 'inbox' SET delete = '1' WHERE mailID = '$mailID1'; ";
mysql_query($sql) 
or die(mysql_error()); 


header( 'Location: ************) ;

?>

Any help? I been beating my head over this.
