Page Nav interaction won't trigger

Hey! So I have been trying to design a page nav for a site I’ve been working on. I copied the page material to a practice project and put it together. I have the thing assembled and one of the two interactions works - Going up and down works, I need to get the interior letter to change to the next.

I had planned to put triggers on divs between the sections or the sections themselves so that it would change at the proper timing. The problem is I can not get the triggers to go when I want. The interaction does not register certain parts of my page as being part of the length of the scroll interaction. Almost like it starts and stops between 25 and 75% of the page since some interactions won’t trigger.

I’m not sure if the problem is how its build or what. The interaction for swapping the letters was only supposed to hide and unhide the proper letter at the proper time.

If you can read my awful writing this is what I was designing.
