One Button, Multiple Text Fields for Multiple Pages

I am working on a course that has a global button. I want that button to be able to show a specific text box depending on the page they are on within the title. I have about 20 small text boxes created with content, for 20 pages. BUT, I want them hidden when the course starts and if the global button is clicked on, say on page 8 of the title, I want the specific text box for page 8 to be visible and no others. What are some steps that I should take? Has anyone done something like this? Thanks in advance!
