Problem with Organizing Views in Folders

[eluser]CARP[/eluser]
Hi guys
I'm having a little problem trying to organize views in subfolders.
I've created (and divided) the views in:

views/inc_header.php
views/inc_footer.php

Then I've a view file stored in
views/parameters/city

And in the view file, I have:

Code:

<?
include("../inc_header.php");
?>

but I'm getting the following

Severity: Warning
Message: include(../inc_cabecera.php) [function.include]: failed to open stream: No such file or directory
Filename: parameters/city.php
Line Number: 2

Thanks a lot in advance for any tip you can give me
