Graphics, Figures & Tables ⇒ Getting Extra \fi error for using subcaption package

[gmbokoma_94]

Hi

Kindly, assist with !Extra \fi error for subcaption package. The package is working perfectly for other projects but not working for this specific one. This error is rising from having \subcaptionbox inside the figure enviroment.

Hi,

welcome to the forum!

There may be an error in your code. Perhaps post your code here as a small, reduced copy (complete with relevant preamble like \documentclass, etc.). That code should bring the error when we test it.

Once we can test the code and see the error, we can fix it most of the time. Without code, a hint is rarely possible.

A quick example to show that it's usually working:

Code: Select all

\documentclass{article}
\usepackage{subcaption,lipsum}
\begin{document}
\section*{Demo of subcaption with subcaptionbox}
\lipsum[1]
\begin{figure}[htbp!]
  \centering
  \subcaptionbox{First dummy image}[.45\linewidth]{%
    \fbox{\rule{0pt}{3cm}\rule{5cm}{0pt}}%
  }\hfill
  \subcaptionbox{Second dummy image (longer caption
    to show wrapping)}[.45\linewidth]{%
    \fbox{\rule{0pt}{3cm}\rule{5cm}{0pt}}%
  }
  \caption{Two subfigures created with subcaptionbox}
  \label{fig:main-fig}
\end{figure}
\lipsum[2]
\end{document}

Hi Stefan

Thank you so much.

Kindly, see attached the attached file. I literally just cut the parts that is giving problem.

[Stefan Kottwitz]

You have this line here:

Code: Select all

\caption{ Numerical, exact solution and absolute error at $T = 5$, with $\Delta t = 0.1$, $\Delta x = 0.12 $ for %Eq.~(\ref{eq-27}).}

Eq.~(\ref{eq-27}).} is commented out by that percent sign, so the closing brace is missing. Remove that % symbol.

Also, I think better move

Code: Select all

\usepackage{BSPMsample}

to the end of the preamble, right before \begin{document}, because it seems to interfere with the other packages otherwise.

Thank you Stefan

The \usepackage{BSPMsample} is a special package for journal submission that I am trying to submit my article too. I can not by pass it. Maybe their package does not support \subcaptionbox, otherwise everything else is good.

[Stefan Kottwitz]

Sure, that's why I suggested keeping it, but moving it to a later place. If you have it on the top, first loaded, the other packages are not only interfering but can also change the journal's settings. If you move it to the end, it applies its settings later, when another package's settings cannot overwrite them. But if you don't have another error, you can keep that, the errors I got may be related to my local LaTeX version.

Dear Stefan

Thank you very much. I have tried re-positioning \usepackage{BSPMsample} but I am still getting the same error. I will probably try to avoid subcaption at all cost. Or is there anyway I can do it?

[Stefan Kottwitz]

I get 0 errors. Perhaps post your updated code and the .log file you get with that code to see the exact error message and related information. I don't get an !Extra \fi error.
