Never mind, I figured it out! In case someone else runs into the same problem, I found that I had a variable that was contradicting the switching of the chapter. I had the conditions be that "if IRRITATION (my variable) is above 3, go to [certain page]." However, since I already had come up with a way to make the player go to that page without IRRITATION being above 3, I guess the variable just...didn't get to do its thing until I clicked on the next link, which happened to be switching to the next chapter. As a result, instead of going to the next chapter, my storygame kept switching to the [certain page] I had told the storygame to do if IRRITATION was above 3. Removing that condition fixed the problem, and allowed my storygame to freely move to the next chapter.
Basically, if you run into this same problem, check your variables and make sure none of them are counteracting your directions for the storygame to go to your next chapter. :) Sorry for the confusion, all caused by me!
