Anybody know how to work this "Display Keyword Script"

[Yellowberry.org]

I can not get it to work it does not display any keywords

http://www.walkingwithtigers.org/popular-keywords.php

I found the script here

http://www.hotlikechilli.co.uk/referring-keywords-display/

but when i checked the code this page

un-official.info

does not work very well.

If someone has a working script or another script please tell me.:confused:
