Get URI segment returns nothing.... [RESOLVED]

[eluser]Frychiko[/eluser]
Hi,

I started using CI yesterday to convert over an online price comparison shop, anyway this problem stopped me dead in my tracks.

I have an URL:

Code:

http://localhost/ci/manufacturer/edit/10

* manufacturer is my controller
* edit is a function within the manufacturer controller

I want to get a URI segment within the edit function with:

Code:

$this->uri->segment(n)

ie.

Code:

function edit() {
   echo "segment:".$this->uri->segment(3);
}

I tried 'n' with values from 0-3 but nothing is returned.

Perhaps I'm missing a configuration setting or something?

cheers,
Frychiko
