Hallo, bin ein Neuling was LaTeX angeht, bin aber sehr fasziniert davon udn dabei es zu lernen.

Das Problem, was ich habe ist, das ich keine PDF dateien erzeuge.

Mal klappt es, mal nicht, obwohl alles gleich ist.

Ich benutze:

Miktex 2.9
TexCenter
SumatraPDF


Ich weiß gar nicht was da alles steht, hier die Fehlermeldung:

! Undefined control sequence.
l.3 \beginn
{document}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Missing character: There is no ß in font cmr10!
