Graphics, Figures & Tables ⇒ Wrapped Figure causes Error

[DPetrov]

Hello everyone, here is my problem:

Code: Select all

\usepackage{wrapfig}
...
\begin{wrapfigure}{r}{width=0.5\textwidth}
  \begin{center}
    \includegraphics[width=0.45\textwidth]{123.jpg} 
    \caption{123}\label{123}
  \end{center}
\end{wrapfigure} 

This piece of code produces the following error.

!Missing Number treated as zero.

I have no idea what that means and I could not find any solutions on the internet. I would be really grateful if anyone helps. Thanks in advance.

Hi DPetrov,

The key=value syntax for options was introduced long time after the birth of LaTeX(2e), and therefore many (older) packages does not follow that pattern.

The wrapfig package is such a package and therefore you have to write this.

Code: Select all

\begin{wrapfigure}{r}{0.5\textwidth}

(especially without width=)
