How many listed in the "layout Boxes controller"?

I added the "google sense" sidebox ,yet it fails to show up in the Tools\layout boxes controller. I noticed that the page is full of items. Is it possible that the reason why the new sidebox fails to show is due to a page that's too full to show additional ones.
If not, I followed the directions to the letter. Yet the google adsense fails to show up. Any ideas?

Confirm that all the files are indeed uploaded to the right place. If they were, you would see it automatically, and there is no "second" page. :-)

Here's how it's set, according to the developers tool kit:
/home/greenene/public_html/zencart/includes/languages/english/extra_definitions/Mihluna/google_box_defines.php

Line #9 : define('BOX_HEADING_GOOGLE_ADSENSE', 'Ads by Goooooogle');

/home/greenene/public_html/zencart/includes/modules/sideboxes/Mihluna/google_adsense.php

Line #8 : * @version $Id: google_adsense.php 2006-06-06 06:06:06Z gilby $

Line #15 : require($template->get_template_dir('tpl_google_adsense.php',DIR_WS_TEMPLATE, $current_page_base,'sideboxes'). '/tpl_google_adsense.php');

Line #17 : $title = BOX_HEADING_GOOGLE_ADSENSE;

it looks right, but I am not sure...

You appear to have a typo ... or spelled a directory name wrong:

mihluna does NOT mean the same thing as Mihluna

Well.... thank you! Capitalizing the directory had not simply crossed my mind.
