WordPress MU

I'm trying to add an admin menu to the site admin. I have followed the directions here http://codex.wordpress.org/Adding_Administration_Menus but have not been able to get it working. Any Ideas I'm using this code:

add_action('admin_menu', 'cdrc_menu');

function cdrc_menu(){
	add_menu_page('Reports', 'Reports', 10, CDRC.'/reports.php',);
}

You might want to get rid of that last ,
