Hide a Page from Logged out users

I’m using this code to make my buddypress site private to logged in users only, but keeping the blog and non-BP pages available to visitors.

‘function sh_walled_garden()


if( ! bp_is_blog_page() && ! is_user_logged_in() )

bp_core_redirect( $bp->root_domain );


add_action( ‘wp_loaded’, ‘sh_walled_garden’ );’

I’m now trying to block access to one specific page. I thought I could do it with the same code like this

‘ if( ! is_page( 697 ) && ! is_user_logged_in() )

bp_core_redirect( $bp->root_domain );’

but I think I’ve got a few too many exclamation marks creating redirects that will never complete.

Any thoughts on how I can block a specific page from view?
