Sidebox on Checkout Pages Only

I created an new override sidebox using the method found here:
https://www.zen-cart.com/tutorials/index.php?article=270

I was able to easily create my sidebox and have it display on the index page only. However, my goal is to post my security validation banner on my log in & checkout pages only.

I cannot figure out how to verify if the checkout page is the current page. I basically want to say " if ($this_is_login_page) then display box" - but with something that works. My code:

if ($this_is_home_page) 
	{ $show_security= true; }
else { $show_security = false;
}		

if ($show_security == true) {
echo' Security Banner Code Inserted Here ';
}
?>

try this:

} else {
$show_security = false;

Thanks Clyde. That did the trick. A note to anyone with the same isue. Make sure to add a single quote ( ' ) before the word login. Otherwise it will not work and for me it disabled other working sideboxes. Final code:
