Dear community,
to create a new layout for my mathematical KOMA book, I used the
mdframed package. I extracted one of the examples from the associated
documentation, but got an error. Then I radically shortened the
preamble so that only the error remained. However, it is still
possible to generate an output (MWE).
I searched Google and Stack Exchange for a long time and made several
attempts to fix the error, but unfortunately failed.
The error message reads:
! Missing number, treated as zero.

l.78 ...in{stz}[\textsc{Pythagoräischer} Lehrsatz]
A number should have been here; I inserted `0'. (If you can't figure
out why I needed to see a number, look up `weird error' in the index
to The TeXbook.)
! Illegal unit of measure (pt inserted).

This line is the problem:
frametitleaboveskip=\dimexpr−\ht\strutbox\relax
Delete it and it should work. Maybe a bug in mdframed or
a change to the keyword frametitleaboveskip

Dimensions can be in units of em, ex, in, pt, pc, cm, mm, dd, cc, bp,
or sp; but yours is a new one! I'll assume that you meant to say pt,
for printer's points. To recover gracefully from this error, it's best
to delete the erroneous units; e.g., type `2' to delete two letters.
(See Chapter 27 of The TeXbook.)
Can you help me, please?
Greetings
Andreas
