<?
$ok=$HTTP_POST_VARS["ok"] ;
if ($ok=='yes')
{
$message="OK!";
mail($femail, $title, $message,"From: $yemail");
$ok='no';
echo "<html><body>".nl2br($message)."<BR><BR><A HREF=index.php>back to the send page</A></body></html><script language='javascript'> alert('Sending successfully!'); </script>";
exit();
}
?>
