Document Classes ⇒ letter.cls

[Richard Davies]

I'm trying to write a simple letter and get errors. Minimal example and errors shown. Same errors if compiling with pdflatex, lualatex or xelatex.

Code: Select all

\documentclass[11pt,a4paper]{letter}
\begin{document}
\begin{letter}
  \opening{Dear Sirs,\\}
  The cat sat on the mat.
\end{letter}
\end{document}

Error message

?

Am I doing something stupid or is there something wrong with my latex?

The {letter} environment requires an argument which you have omitted.
\begin{letter}{recipient of this letter}

Thank you just me being an idiot.

Hi Richard,

welcome to the forum!

No worries, small code mistakes happen easily to all of us and it's good that solution and explanation was easy.
