header.php conditional is not working

Hello!

I want to have a background slider only in homepage, all other pages will have a static background image.
I have the following conditional on my site (header.php) to change the background outside the home page but is not working. Really frustrated here!

<?php
if ( is_home() || is_front_page()) {
require_once(TEMPLATEPATH . ‘/slider.php’);
}
else {
require_once(TEMPLATEPATH . ‘/slider2.php’);
}
?>

Also I have a /#!/ on the theme url, is this causing this malfunction?

Thanks in advance.
