I created a counter named foo to add up so money which I want to get from my boss. When having an itemize environment the counter is reset accidently. Does anyone know why or how to solve problem (so tell my what I am doing wrong ;-) )? I added comment lines to clear up what I want to do. Everytime I add a value of money, the sum is created.

\documentclass{scrbook} %\usepackage{eurosym} %\newcommand{\eu}[1]{\advance\foo by #1 \EUR{#1}} \begin{document} Create Counter: \newcount\foo Give counter: \the\foo Increase by three: \advance\foo by 3 Give result: \the\foo \begin{itemize} \item Increase by seven: \advance\foo by 7 %\item \eu{7} \item Give result: \the\foo \end{itemize} Give result: \the\foo \end{document}

The PDF looks like:

Create Counter:

Give counter: 0

Increase by three:

Give result: 3

• Increase by seven:

• Give result: 10

Give result: 3

I use texniccenter with Miktex 2.9 on a Win7 64 machine.

    tex.stackexchange.com/questions/35084/… might help here: you are using a 'raw' TeX count register rather than the LaTeX wrapper as a counter, and you therefore have to allow for grouping. Commented Aug 19, 2014 at 7:50

    Any environment is a single group. So everything you are doing inside this group is local. Using some values outside a group you have to work with \global. Using expl3 gives you some more options. Commented Aug 19, 2014 at 7:52

Reset to default

These are TeX-core counters, which work locally. You would have to use \global\advance. However, I suggest using LaTeX counters, which are global by default:

\documentclass{scrbook} \begin{document} Create Counter: \newcounter{foo} Give counter: \arabic{foo} Increase by three: \addtocounter{foo}{3} Give result: \arabic{foo} \begin{itemize} \item Increase by seven: \addtocounter{foo}{3} \item Give result: \arabic{foo} \end{itemize} Give result: \arabic{foo} \end{document}

  • Thank you very much. Before asking this question I tried this way, because I read it in another topic. But obviously I did another mistake. Commented Aug 19, 2014 at 7:55
