BB Press Favourite Tab

Hello,

I installed both WP Favorite Posts and BuddPress. And i would like to show favorite posts of the user in buddypress tab.

I created a tab using this code;

function my_test_setup_nav() {
	global $bp;

	$parent_slug = 'test';
	$child_slug = 'test_sub';
//name, slug, screen, position, default subnav
	bp_core_new_nav_item( array( 'name' => __( 'test' ), 'slug' => $parent_slug, 'screen_function' => 'my_profile_page_function_to_show_screen', 'position' => 40, 'default_subnav_slug' => 'test_sub' ) );

/* Add the subnav items to the profile */
// name, slug, parent_url, parent slug, screen function
	bp_core_new_subnav_item( array( 'name' => __( 'Home' ), 'slug' => $child_slug, 'parent_url' => $bp->loggedin_user->domain . 'test/', 'parent_slug' => $parent_slug, 'screen_function' => 'my_profile_page_function_to_show_screen' ) );

	bp_core_new_subnav_item( array( 'name' => __( 'Random Stuff' ), 'slug' => 'random', 'parent_url' => $bp->loggedin_user->domain . 'test/', 'parent_slug' => $parent_slug, 'screen_function' => 'my_profile_page_function_to_show_screen234' ) );

	function my_profile_page_function_to_show_screen() {

	//add title and content here - last is to call the members plugin.php template
	add_action( 'bp_template_title', 'my_profile_page_function_to_show_screen_title' );
	add_action( 'bp_template_content', 'my_profile_page_function_to_show_screen_content' );
	bp_core_load_template( apply_filters( 'bp_core_template_plugin', 'members/single/plugins' ) );
	}
	function my_profile_page_function_to_show_screen_title() {
		echo 'something';
	}
	function my_profile_page_function_to_show_screen_content() { 

	$favorite_post_ids = wpfp_get_users_favorites($GLOBALS['bp']->displayed_user->userdata->user_login);

	}
	//random page content:
		function my_profile_page_function_to_show_screen234() {
		//add content here - last is to call the members plugin.php template
	add_action( 'bp_template_content', 'my_profile_page_function_to_show_screen234_content' );
	bp_core_load_template( apply_filters( 'bp_core_template_plugin', 'members/single/plugins' ) );
	}
	function my_profile_page_function_to_show_screen234_content() { 

	echo 'This is a random page.';

	}
}
add_action( 'bp_setup_nav', 'my_test_setup_nav' );

But i could not load WPFP on this tab. There is a snippet which is a screen function:

$fav_array = wpfp_get_users_favorites(bp_get_member_user_id());

But i don’t know where to put. And also, if there is anything to change in the code.

Thank you in advance.
