[O] using Agenda org-agenda-files variable

[Renato Pontefice]

Hi,

following this tutorial
"http://orgmode.org/worg/org-tutorials/orgtutorial_dto.html"

at this point:

"A taste of advanced features"

it's written to add this text, on my init.el file (I'm working on win).

(setq org-agenda-files (list "~/org/work.org"
                             "~/org/school.org" 
                             "~/org/home.org"))

I've done it.

Continuing the tutorial, I find some operation to do in my org file "Press C-c a t to enter the global todo list"

I do that, but I receive in the *Org Agenda* buffer, the following text:
_________________________________
Global list of TODO items of type: ALL
Available with `N r': (0)[ALL]
__________________________________

and nothing else.

I have on my 1.org the following line:
*** configure
   SCHEDULED: <2014-01-08 mer>

So, I'm expecting, that i could find at least this TODO line on the Agenda. But nothing...

What I've done wrong?

Do someone can link me some page example? Or something similar where I can get help?

TIA

Renato

ps

I don' t find the file work, school and home .org, on the folder where my org file (1.org) are stored :-( )
