No he’s saying the “Sections” you are linking to need an “ID” typed into the section first. You may have done that, but your page seems a little chaotic. Try deleting this page. Start over and do a simple 3 or 4 section of blocks that span full width, each 900px. Set each section with an ID. Then add a top div as the header, put a button in it and link it.
Try fresh.
