I'm trying to make a custom menu that only gives you the options once you have walked through my tour page by page, step by step.

So if you've been to page 3, you can see the links to page 1 and 2 - but not 5 or 6.

As you go through the site, your options increase.

1. Homepage.
2. Homepage - Page 1
3. Homepage - Page 1 - Page 2
4. Homepage - Page 1 - Page 2 - Page 3

etc etc

How would you accomplish this?
