xprofile_screen_display_profile

oops wrong function. This will add a sub nav under profile called Page. I don;t think you can change the slug for this item for different pages. What you would want is /page/name-of-page/

In BuddyPress the part after /page/ would be considered an action variable. So you could do a looopy of some sorts to get the action and match it up to a page.

Example code to read the variable and then you could display an appropriate page. if you visit /page/2/ it will echo the string. action variables are anything after an action. page is the action so anything in between slashes = variable and they are stored in an array.

if you had this in the url:
page/2/3/4/

the variables can be accessed like this:
$bp->action_variables[0] = 2
$bp->action_variables[1] = 3
$bp->action_variables[3] = 4

`function bp_page_nav(){
global $bp;

$user_domain = bp_displayed_user_domain() ? bp_displayed_user_domain() : bp_loggedin_user_domain();

$profile_link = trailingslashit( $user_domain . $bp->profile->slug );

bp_core_new_subnav_item( array(
‘name’ => ‘Page’,
‘slug’ => ‘page’,
‘parent_url’ => $profile_link,
‘parent_slug’ => $bp->profile->slug,
‘screen_function’ => ‘page_screen’,
‘position’ => 20

) );
}
add_action(‘bp_setup_nav’, ‘bp_page_nav’, 10 );

function page_screen(){
global $bp;

add_action( ‘bp_template_content’, ‘bp_page_screen_content’ );

bp_core_load_template( apply_filters( ‘bp_core_template_plugin’, ‘members/single/plugins’ ) );
}

function bp_page_screen_content(){
global $bp;

$variable = $bp->action_variables[0];

if( $variable == ‘2’ ){
echo ‘page 2’;
}

}
