Hello, Sarah!
The option to hide all subsequent questions does work – it will hide all the rest of the questions, and then you'll need to add triggers to show those questions, just like you would normally use for a show/hide on an individual question. Sorry the confusion! :-(
Aside from that, I don't think this feature will give you the result you want. It sounds like you actually want a separate question on each page. You'll want to add in some pages first, and you can do this by clicking on the silver “Add Page” button in your “Edit Survey” tab. Now you can either start adding in a question for each page, or if you already have your questions, click on the “Reorder Questions” link just under your “Edit Survey” tab. From here, you can click-and-drag questions from one page to another.
