index method is "found" but other methods not.

i am trying to query the url for variables.
i thought i could do something like:

Code:

$rot1=$this->uri->segment(0);
$rot2=$this->uri->segment(1);
$rot3=$this->uri->segment(2);

the url looks like:

Code:

http://localhost/myapp/mymethod/123/456/789

i would like the rot variables to contain 123, 456, 789 respectively.
thanks
