I don't know why when I compile my project with xelatex this command gives me an error and is not showing in pdf.
The command is the openepigraph command:
\newcommand{\openepigraph}[2]{%
%\sffamily\fontsize{14}{16}\selectfont
\begin{fullwidth}
%\sffamily\large
\begin{doublespace}
\noindent\allcaps{#1}\\% epigraph
\noindent\allcaps{#2}% author
\end{doublespace}
\end{fullwidth}
}
Here is an example:
\openepigraph{En este capítulo veremos los tipos de enlace entre átomos, concepto de cristal, redes de Bravais, concepto de base, planos y direcciones cristalinas, estructuras relevantes.}{GUÍA}
This are the errors that gives me:
I didn't make this command, I copied form an Overleaf sheet and I don't know why in pdflatex works but in xeltaxe or lualatex doesn't.
Thanks for reading
