WP_die when setting up custom plugin sub menu. Why?

I'm building a custom plugiin, which is going great... I have hit a snag when trying to add a sub menu item where I keep getting the wp_die message that I do not have sufficient rights, which are the same as the amin page, and that one works. Code below.

<?php
function lsmcustom_options_menu_2() {
    // add_menu_page( $page_title, $menu_title, $capability, $menu_slug, $function, $icon_url, $position );
    add_menu_page(
        'Test area',
        'Custom Plugin 2',
        'manage_options',
        'lsmcustom-plugin-2',
        'lsmcustom_options_page_2',
        plugins_url( 'Custom_Plugin_2/images/L-icon.png' )
    );

    // add_submenu_page($parent_slug, $page_title, $menu_title, $capability, $menu_slug, $function);
    add_submenu_page(
        'lsmcustom-plugin-2',
        'Manage',
        'Manage',
        'manage_options',
        'Manage publishers',
        'lsmcustom_manage_page'
    );

}

add_action( 'admin_menu', 'lsmcustom_options_menu_2' );
?>

Any ideas?

I think I have just realised my error, I may have included the function called from within the page set up with the wrong hook. Will let you know.

EDIT... nope. That was not it.

Fixed it... turns out the menu-Slug doesn't allow spaces :)

<?php

function lsmcustom_options_menu_2() {
    // add_menu_page( $page_title, $menu_title, $capability, $menu_slug, $function, $icon_url, $position );
    add_menu_page(
        'Test area',
        'Custom Plugin 2',
        'manage_options',
        'lsmcustom-plugin-2',
        'lsmcustom_options_page_2',
        plugins_url( 'Custom_Plugin_2/images/L-icon.png' )
    );

}

function lsmcustom_mange_menu_2() {

    // add_submenu_page($parent_slug, $page_title, $menu_title, $capability, $menu_slug, $function);
    add_submenu_page(
        'lsmcustom-plugin-2',
        'Manage',
        'Manage',
        'manage_options',
        'Manage_publishers', // was 'Manage publishers'.. this was wrong :(
        'lsmcustom_manage_page'
    );

}

add_action( 'admin_menu', 'lsmcustom_options_menu_2' );
add_action( 'admin_menu', 'lsmcustom_mange_menu_2' );

?>
