Thanks guys, that was my problem I was looking at Packs instead of Sets. I had also tried clicking on the Set's link, rather than hovering over it, so that displays a blank page which further complicated it.

Yeah. Unfortunately Google Sites doesn't have the ability to make a placeholder menu item - it has to point to a page. I've put some text on both the Packs and Sets pages now that will direct you to the right place, so that should be less confusing. I also added a bit of a key describing where to find what on the Home page.

Good idea!

BTW, looks like you just copied text from Sets page to Packs, and forgot to change the last word from "Sets" to "Packs".

Hover over the menu item to see the different sets.
