Problem with references \here \where

Question

Hi I have a problem with referencing which I cannot reproduce with the MWE. Here is what the problem is. I need to write next to the page number of my reference also if that page comes before and or after (Cf. above P. X - cf. below P. Y).

For that I am using following definition:

\makeatletter%
\newcount\here@undef%
\newcommand{\here}[1]{%
  \@ifundefined{here@#1@undef}{}{\advance\here@undef by -1}%
  \@namedef{here@#1}{}}%
\newcommand{\where}[1]{%
  \@ifundefined{here@#1}{%
    unten\space%
    \@ifundefined{here@#1@undef}{%
      \@namedef{here@#1@undef}{}%
      \advance\here@undef by 1%
    }{}%
  }{%
    oben%
  }%
}%
\AtEndDocument{%
  \ifnum\here@undef>0%
    \GenericWarning{}{There were undefined above/below labels}%
  \fi}%
\makeatother%

and than in the text I put: \here{x}\label{x} and \footnote{Siehe dazu \where{x} S. \pageref{x}.}

Now that works fine for the most parts but there are some entries where it doesn't meaning it tells above when its below or below when its above.

Here is an example:

The page number is ok but it should be oben (above) instead of below (unten). This happens only with few references - not with all, but still thats a problem and it shouldn't happen.

I can't figure out why it does this.In the .aux file it looks like this:

\@writefile{toc}{\defcounter {refsection}{0}\relax }\@writefile{toc}{\contentsline {subsubsection}{\numberline {1.2.2}Homoousianismus}{36}{subsubsection.1.2.2}}
\newlabel{hmsnsnms}{{1.2.2}{36}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZGHPAZ8A62}{{1.2.2}{36}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZGGRAAN9M3}{{1.2.2}{36}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZGF97PS312}{{1.2.2}{37}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZENP2OXA6Z}{{1.2.2}{37}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZDNOW6A981}{{1.2.2}{38}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{athglbkntns}{{1.2.2}{38}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZBT29MH2LW}{{1.2.2}{38}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZAPYHEWQ07}{{1.2.2}{39}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{ZA4HNDP59U}{{1.2.2}{39}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{Z546N43KIX}{{1.2.2}{39}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{Z50RQN9QUC}{{1.2.2}{39}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{Z4RSFUMEBP}{{1.2.2}{39}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{Z2ZXAGGBHJ}{{1.2.2}{39}{Homoousianismus}{subsubsection.1.2.2}{}}
\newlabel{doppltexath}{{2}{40}{Homoousianismus}{Item.29}{}}
\newlabel{Z0H2OLHK3K}{{1.2.2}{42}{Homoousianismus}{Item.30}{}}

The problematic reference is:

\newlabel{doppltexath}{{2}{40}{Homoousianismus}{Item.29}{}}

and I get it that the reason for this is that here I have {2}(second chapter) instead of {1.2.2} (first chapter), but I can't figure out why he is doing this with exactly this entry which is just a normal entry like any other (nothing special about it).

Here is a MWE but as I mentioned I can't reproduce this behaviour:

Also and I think that is very important this only happens with Cf. below and not with Cf. above references!

I also uploaded my .tex and .aux files here if someone wants to take a look at them:

Thanks for your help!

Answer 1

I can reproduce the issue if I enclose \here in an environment:

\begin{quotation}
\blindtext\here{x}\label{x}
\end{quotation}

Then the second \where will say “unten” instead of “oben”. The problem is that \@namedef and \advance act locally, so their action is undone at the end of the environment.

Use \global in front of \@namedef and \advance. Also, omit % after constants.

This will print
