Thank you! I put “exit title” in a separate chapter and that seems to be working.
New problem: I added test results. When the checkmark button on the test results page is set to go to the page in the last chapter with the exit title action, the publish error tells me that only “prev/next page” actions are permissible in random mode. But when I change that button on the results page to go to the next page, it selects a page from the test and does not go to the next chapter.
