Hello, I want section headings to be in capitals, but when I use: \setuphead[section][style=cap] I get an error as follows: ! Argument of \getvalue has an extra }. <inserted text> \par <to be read again> } \uppercased ...d \xdef \@@expanded {\uppercase {#1 }}}\@@expanded \dodosmallcapped ...alize \cap@@uppercase {#1{#2}} \egroup \doplaceheadnumbertext ...o #1}\c!style \getvalue {\??ko #1\c!command }{\dos... \dodododoconstructhead ...{\finalsectionnumber }}} \writesection {#1}{#3}{#4}... l.58 \section{Introduction} Most other options seem to work, e.g. \setuphead[section][style=bold] But \setuphead[section][style=\cap] has same problem as above. I would try it in the "ConTeXt online" but that doesn't seem to be working. Thanks, Richard P.S. How do I get a full stop after the section number?
