I did point it out that you had duplicate pages Heather in my email to you:

I can't understand why you have duplicates of all your pages and why the names are duplicated though
The good news is that you can select the desktop page and Copy it into a new Xara file, so the only page you need to recreate is the index (home) page.

From there you need to create a variant of your website and adjust the placement of text, images into a 480 px site.
