How can I display the Loging only under one page sidebar

This is the website.
https://semperscotland.org.uk
I want to display the loging widget when someone click the page called Member’s Area.

I alreay have tried something like that but it didn’t work.

global $post; return (is_page(‘Members Area’) || ($post->post_parent==”197″));

Thanks for your help in advanced.
