Hiding a page

[PedroDousseau]

So, i am using onepagescroll and he is doing great until now, but i have a quick question:

My website has 7 pages in total, but 1 of the pages (page5) can't be displayed at first. It can only show up when user click at the button.
My question is, how can i "hide" that one page? I tried to set display:none but it only hides the page's content, not the page itself.

Thanks!
