This is a code I have downloaded from http://www.ajaxprojects.com/ajax/tutorialdetails.php?itemid=9

 

But when I run this code on my server - I get a strange error on this page - http://snipurl.com/1ssd9

 

Why is this error been caused, and how can I fix this in my code?

 

I cant copy the error but you can see it on this link: http://snipurl.com/1ssd9
