help with UPDATE query!!

[hoax_monkey]

Hi I am having trouble trying to update multiple fields within my customer table. I think I have something wrong with my query? If anyone can help I would b grateful, Thanks

$query = "UPDATE customer SET (email, addr1, addr2, addr3, addr4, postcode, telephone) VALUES ('$e', '$a1', '$a2', '$a3', '$a4', '$pc', '$te')  WHERE customer_id={$_SESSION['customer_id']}";

Also Im not sure if this works but I am retrieving the current email address from the database and displaying it within the text box by setting the value='email', I then want to change the email address and UPDATE the database but I'm not sure if I can do it this way?

<p><b>email:</b>

<?php // Retrieve the email address and add to field.
$sql = "SELECT email FROM customer WHERE customer.customer_id = {$_SESSION['customer_id']}"; 	
$result = @mysql_query($sql) or die("Couldn't execute query!"); 
while ($row = mysql_fetch_array($result)) { 
$email = $row['email']; 
echo "<input type='text' name='email' size='40' maxlength='40' value='$email'>";  

}
?>
