LyX ⇒ "missing number, treated as zero" error while adding image

[omer21]

I get "missing number, treated as zero" error, while adding figure. But when i extract the figure there is no error everything is normal. Here are my settings:

Code: Select all

\documentclass[english,turkish,a4paper,10pt,3p,times]{elsarticle}
\usepackage{mathptmx}
\usepackage[scaled=0.9]{helvet}
\usepackage{courier}
\usepackage[T1]{fontenc}
\usepackage[latin5]{inputenc}
\usepackage{float}
\usepackage{units}
\usepackage{amsthm}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{esint}

And the error i get:

I think you want to look at the first error, not the last. The ones following the first one might be caused by it. I'm not sure what "missing \endcsname" means.

Exactly! @omer21: Welcome to the LaTeX community! Could you by any chance attach an example document with example figure to the forum so we can reproduce the error? A LyX equivalent of a minimal working example so to speak...

I'm not sure what "missing \endcsname" means.

In TeX you can call macros not only by their name but also but enclosing the name between \csname and \endcsname. This is useful when programming TeX when you want to call a macro whose name is constructed. If the \endcsname is missing you get this message. There are various possibilities why this happens and it is difficult to say without the actual document.

Thanks for the explanation!

Thank you for your replies.

I attach the piece of my document which gives the mentioned error.

Ok, this one wasn't obvious... The problem is the combination of the language setting to Turkish and the scaling of the image.

Your document uses babel for the language settings which is a good thing. However, babel turns some characters into active ones. An active character is for TeX the same as a macro. In case of Turkish the active characters are :, ! and =.

The scaling of the image to 70% results in the LaTeX command:

Code: Select all

\includegraphics[scale=0.7]{image}

which you can see if you look at the source. And here's the problem: the = is active here but it shouldn't be. So what you need to do is turn it inactive temporarily. For turning an active babel character into its normal meaning babel has the \shorthandoff{<char>} command. If you place it directly before the image compilation goes fine and the redefinition stays local since the image is included inside a LaTeX environment.

You do this by inserting the ERT \shorthandoff{=}:

Ooo you are very good. Thank you very much. Now everything is fine.
