Can you give us a link to the published site?

When you preview the site in DP do you see the second page?

This has nothing to do with the problem but your pages should have descriptive page titles, such as About, Contact, etc. Your second page is index-a because when you add a new page Xara automatically uses the name of the previous page and adds the -a or -b, etc. You can change this in the Web Properties ? Page tabbed section in the Title box.
