Hi Alexander,
Great question, thanks for posting it on the forum!
For some background from our converstion, it seems like you have your closed captions distributed across each of your pages with a "cc" button that toggles the visibility of the caption text. We can create a variable that remembers whether the caption text was shown (or not shown) and use that to show (or not show) the caption text when each new page loads.
Here's how -
