Hi Wolfgang
Did my first tabulate/itemize example work for you?
I have no problem including your graphic in a table although the size isn't perfect.
\starttext
\startplacetable[title={some caption},reference={fig:somefig}] \startitemize[a][stopper=)] \starttabulate \NI \startMPcode input heap ; \stopMPcode \NC\NR \stoptabulate \stopitemize \stopplacetable
\stoptext
Without the actual error message it's hard to tell what's wrong but I guess your installation doesn't know the \NI command for tabulate.
The best would be to update your three year old ConTeXt version.
It seems so I tried to update everything using the latest distributeion of texlive for Ubuntu 18.04 form launchpad.net jonathanf but it seems as he does not really verify the context and luatex packages. Do you know a wroking ubuntu debian repo/ppa for installing context and all related? Alternatively as i do get lua errors what luaversion would you recommend and what additional lua packages are necessary possibly not considered by jonathanf? What alternative installation packages do you recommend exempt compiling from sources? Best Xristoph -- -- Christoph Hintermüller Dipl.-Ing. Dr. MBA.
