Module URLs and arguments

Hi guys,

I have a question about the hook_menu function.

In my module i want to define a few URL's that take arguments, which i then use to filter data.

My menu hook looks like this

function clubinfo_menu()
{
	$items = array();

	//this is added for this current tutorial.
         $items['klubber/%league/%klub/trup/%spiller'] = array(
		'title' => t('Spiller'),
		'page callback' => 'clubinfo_render_player',
                'page arguments' => array('','',0),
		'access arguments' => array('access clubinfo content'),
		'type' => MENU_CALLBACK
	);
          $items['klubber/%league/%klub/%tab'] = array(
		'title' => t('Info'),
		'page callback' => 'clubinfo_render',
                'page arguments' => array('','',''),
		'access arguments' => array('access clubinfo content'),
		'type' => MENU_CALLBACK
	);
          $items['klubber/%league/%klub'] = array(
		'title' => t('Klub'),
		'page callback' => 'clubinfo_render',
                'page arguments' => array('',''),
		'access arguments' => array('access clubinfo content'),
		'type' => MENU_CALLBACK
	);
         $items['klubber/%league'] = array(
		'title' => t('Liga'),
		'page callback' => 'clubinfo_render',
                'page arguments' => array(''),
		'access arguments' => array('access clubinfo content'),
		'type' => MENU_CALLBACK
	);
	$items['klubber'] = array(
		'title' => t('Klubber'),
		'page callback' => 'clubinfo_render',
		'access arguments' => array('access clubinfo content'),
		'type' => MENU_CALLBACK
	);       
	return $items;
}

And i've defined these load functions

/* Path arguments loaders START */
function league_load($string){
    return $string;
}
function klub_load($string){
    return $string;
}
function tab_load($string){
    return $string;
}
function spiller_load($string){
    return $string;
}
/* Path arguments loaders END */

All my menu's call the function clubinfo_render, which atm just prints out it's function arguments, and looks like this:

function clubinfo_render($league,$klub,$tab)
{
    print('$league: '.$league.'<br/>');
    print('$klub: '.$klub.'<br/>');
    print('$tab: '.$tab.'<br/>');
    print('sizeof(func_get_args()) : '.sizeof(func_get_args()).'<br/>');
    print_r(func_get_args());
}

My problem is that the arguments from the URLs aren't moved down to my clubinfo_render function.

For instance, if i call this URL http://domain.com/Klubber/JACK-JONES_LIGAEN i expect to get 'JACK-JONES_LIGAEN' as an argument in the clubinfo_render function, but i get nothing.

Caling this URL prints out this output:
$league:
$klub:
$tab:
sizeof(func_get_args()) : 3
Array ( [0] => )

Likewise i'd expect this URL http://domain.com/Klubber/JACK-JONES_LIGAEN/Bjerringbro-Silkeborg/info to suply my function with these arguments 'JACK-JONES_LIGAEN' , 'Bjerringbro-Silkeborg' and 'info'.

Caling this URL prints out this output:
$league:
$klub:
$tab:
sizeof(func_get_args()) : 3
Array ( [0] => [1] => [2] => )

Something must be wrong in my code, can anyone see where the error is, i'm lost?

Martin
