Hi @ChristianHupfer! May I ask you a question about `xcntperchap`? Is there a possibility to access the numerical value of `\ObtainTrackedValue`? Today I tried to do something like the following example, but when I tried to use it as the endpoint of a foreach-loop, I get an `Illegal unit of measure (pt inserted` error.
\documentclass{beamer}
\usepackage{tikz}
\usepackage{xcntperchap}
\RegisterCounters{section}{subsection}
\setbeamertemplate{headline}{%
\begin{beamercolorbox}[wd=.3\paperwidth,ht=2.25ex,dp=1ex]{subsection in head/foot}%
