I try to add a star rating system to my websites: http://www.linknrank.com
But I failed to make downloaded php file work. Complete code and doc at http://www.linknrank.com/phpsoft_5-stars_rating.zip
After I followed instruction in the "readme" file, nothing showed up but a blank page. And you can run and see the result at
(the rating drop-down box)

I know nothing about PHP programming, so, please help me!!!
