The box at the end of the page "zurück" should lead to the last step before. Right now it kind of destroys the page because after using it you cannot use "nächster Abschnitt"/next anymore.

Detailed explanation:
First time loading the page the "nächster Schritt" (next) worked well. If you click on "zurück" it is still working and goes one page back. But after that you can never go to the next step anymore (just with reloading the page) even though it would tell you it is the next Seite, it is not showing the content of it.

The error is everywhere in the intros so it should be one of the general Intro files (input -> studifinder).

To compile: python3 tex2x.py studifinder
