Scaffolding problem (from "Create a blog in 20 minutes" video tutorial)

[eluser]sn_pst[/eluser]
Hello,

I follow the beginner tutorial “Create a blog in 20 minutes” from codeigniter website.
http://codeigniter.com/tutorials/
I use XAMPP.

I try to test the scaffolding feature. I successfully display the scaffolding main page, where there’s a link to “View Records”
(In the tutorial, I got to the point where I successfully display http://localhost/codeigniter/index.php/blog/scaffolding)

When I click the "Create new record" which points to http://localhost/codeigniter/index.php/b...olding/add, it directs me to http://localhost/xampp
instead of bringing me to the add page. Why is this?

Can someone please advise?
Thank you in advance for all the help.
