# Missing $error using htlatex Running the code posted in this question, the first code shown there, posted by the accepted answer by Andrew Swann. When running the code through htlatex on texlive 2012 debian, I get the error htlatex index.tex This is pdfTeX, Version 3.1415926-2.4-1.40.13 (TeX Live 2012/Debian) restricted \write18 enabled. entering extended mode LaTeX2e <2011/06/27> .... (/usr/share/texlive/texmf-dist/tex/latex/amsfonts/umsb.fd) ! Missing$ inserted. \$ l.28 \end{align*} ?

No errors when running latex nor pdflatex on the same code.

Any idea what causes this error? ps. here is a copy of the code just in case. (it will be nice if one can have a direct links at stackexchange to posted code fragments within messages, so that it is easier to point someone to a specific code on a web page).

• Works like a charm, here. Have you tried updating your packages? May 23 '13 at 22:00
• @Jubobs I am on debian system, and hence I use texlive debian. I have latest version 2012. I can't use the texlive update package tlmgr tug.org/texlive/tlmgr.html to update. I have to use debian package manager and so I am stuck until the repository there is updated to texlive 2013? I would not know how to update specific pakcages and all that with debian texlive. I need to go search to see if/when texlive 2013 can be used on my linux (it is mint/debian OS linux) May 23 '13 at 22:05
• I would be very surprised if it didn't work out of the box, but I understand if you want to stick to the package manager. Besides, @Jubobs, it should be noted that the linked question received an accepted answer well before TL2013 went public, so there shouldn't be any issues. Jul 23 '13 at 14:55
• (And nice idea about the point-to-code-fragment feature! Might I suggest you give that a shout-out over at meta.SO?) Jul 23 '13 at 14:57
• I do see the issue here with a bang-up-to-date TL2013. Aug 17 '13 at 7:32

Two issues:

• $$..$$ in \mydmath definition. Change into \ensuremath{..}.
• \adjustlimits gives trouble for tex4ht. The idea is to define it as \relax for tex4ht. This can be done via configuration file, e.g.,

foo.cfg:
\Preamble{html}
