Should be simple (PHP)... PHP noob

1

my PHP page (just sending one var from flash and trying to insert into db) is throwing this error:

Parse error: parse error, unexpected $ in /home/virtual/site382/fst/var/www/html/php/notification.php on line 20

line 20 is where i close the php block with ?>

here’s my code if anybody can help it would be most appreciated!:

<?php 
//this line includes the database connection variables
include_once("config.php"); 
$email=$_POST['email'];


if ($email){
$query= "INSERT INTO 'notification' ('email') VALUES ( '$email')"; 

$results = mysql_query( $query );
 // print out the results
   if( $results )
   {
      echo( "Successfully saved the entry." );
   }
   else
   {
      die( "Trouble saving information to the database: " . mysql_error() );
   }
?>
