here is the error:

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\monique-designs\ADMIN\reponse-to-customer.php on line 96

I think it is on part of WHERE cus_id='$id'

but im not really sure.. please help..

Resource variable $result is null. You need to verify the value of id and also the result of SQL statement.

$result = mysql_query("...... ");      
if($result) {
  while($row = mysql_fetch_array($result)) {
    ...
  }
}

Important: Do not use mysql_* extension. Always use MySqlI or PDO.
