There are two oqmath-files (one for geometry, one for statistics) that are still missing. I made it available, here on libresource.
I see the errors but do not know why they are there, e.g. titles, umlaute. source code seems quite ok to me.

P.S.: "stat-komma.oqmath" and "geo-komma.oqmath" are the files' names. additionaly several images have been added
