Pages question for 1.52 version: ascending and descending

Hi all,

I have a guestbook page that works just fine but the posts show oldest first. How do I show newest first?

This is my GB code: https://www.elyonline.co.uk/temp.txt and this is the guestbook: https://www.elyonline.co.uk/guestbook/

Any ideas?

Thanks a lot
Karl
