Hallo,

die Lösung für das Problem ist nicht trivial, scheint es... Was in laufenden Text problemlos mit \ifnum funktioniert, klappt nicht im Fuß.

Nach langem Recherchieren funktioniert jetzt der nachfolgende Code, aber elegant ist in meinen Augen echt was anderes. Da ist ja fast so schön wie Brainfuck :)

%% definition of the custom IMTEK letter foot ================================================
\RequirePackage{totpages}

%% Unfortunately, a simple \ifnum .. \else .. \fi does not work:
% \ifnum\value{TotPages}>0
% \arabic{TotPages} - \theTotPages mehrseitig: \ref{TotPages}
% \else
% \arabic{TotPages} - \theTotPages einseitig: \ref{TotPages}
% \fi

%% from endheads.sty --------------------------------------
% Essentially these routines are code posted by Heiko Oberdiek to
% comp.text.tex. If you set a counter from a |\pageref|, that
% |\pageref| is undefined on the first run, and \TeX\ will not only
% complain about the undefined reference, but give a ``missing
% number'' error if you try to do anything with that reference, such
% as compare one page number to another. These commands enable one to
% use the |\pageref| without generating the missing number error on
% the first run.
