Undefined control sequence \maketitle apa6 journal

Question

I am making a journal with apa6 but when I make all the preamble, and put the make a \title command the editor says

undefined control sequence line 11

(which is \maketitle). My code:

\documentclass[jou]{apa6}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage[afilliation]
\title{La tutela como mecanismo}
\twoauthors{Mariana)}{Jose}
\leftheader{Jaramillo, Aristizabal}

\abstract{aqui va el abstract}
\keywords{palabras clave}
\begin{document}
\maketitle 
yo llevare 



\end{document}

Answer 1

Two problems:

• the affiliations for the authors are missing, add \twoaffiliations{Affil. of 1st Author(s)}{Affil. 2nd Author(s)}

• the syntax \usepackage[afilliation] is wrong, there should be {} around the package name. Anyway this package seems not to be included in standard tex installations and not available from ctan, so I cannot say if it would work if the syntax error would be fixed...
