Hi, I just updated lmtx, and a file that compiled without errors is now

returning errors. I don't know why.

Thanks Fabrice

Not easy without a small complete file to test. But the first thing I noticed was \im {\text{E\times F}}. That seems conceptually wrong, and the \times inside the \text is not done in math mode. But as Wolfram just wrote, please make a small test file showing also the definition of \coord.

/Mikael

PS \mtext is preferred over \text for text in math.

As for the number of arguments, it's my fault because I modified this macro for another file and forgot to modify it again for the problematic file.* I almost always use it in text mode.* I also have a problem with another macro that I haven't modified, but no works since my update. ########################################################################################## \protected\def\card#1{\m{\mfunction{Card}\thinspace#1}} ########################################################################################## tex error > tex error on line 366 in file ./chapter-5.tex: Missing { inserted <to be read again> \endgroup <macro> \math_m_nop #1->\relax \ifmmode #1\else \normalstartimath \usemathstyleparameter \mathematicsparameter \c!mathstyle \expand \everyinsidemathematics \relax \begingroup #1\endgroup \normalstopimath \fi <macro> \vector #1->\starttikzpicture [thick,baseline=(arg.base),>=stealth] \node [inner xsep=0pt] (arg) {\m {#1} }; \draw [->,shorten >=-1pt ] (arg.north west) -- (arg.north east); \stoptikzpicture <argument> \vector {_} \cdot \vector {k=1} <macro> \math_m_nop #1->\relax \ifmmode #1 \else \normalstartimath \usemathstyleparameter \mathematicsparameter \c!mathstyle \expand \everyinsidemathematics \relax \begingroup #1\endgroup \normalstopimath \fi <argument> \mfunction {Card}\thinspace \prod _{k=1} ^{n}A_k ... \card{\prod_{k=1}^{n}A_k} =\prod_{k=1}^{n}\card{A_k}. 356 \card{A\times B}=\card{A}\times \card{B}. 357 \stopformula 358 \stopproposition 359 \startproposition 360 {Cas général} Soient un entier \m{n\geqslant 2} et \m{A_1, A_2, \dots, A_n}, \m{n} ensembles finis.

You create your command with 3 argument but pass only 2 arguments and whatever follows it as third argument.

Do you even use it in text mode or can \math be removed from the definition?
