Hi Wolfgang, In the first example, so I do not need the command \currentheadnumber but just do : \setuphead [chapter] [command=\HeadTitle, headstyle=\ss, numbercommand=\Headed] But in this second example, using the command \determineheadnumber[chapter], the chapter number is always 0 \setuppagenumbering[location=footer] \startusableMPgraphic{NumberHead} picture r ; r := image ( graphictext \MPstring{chapter} scaled 4pt withfillcolor \MPcolor{lightgray} withpen pencircle scaled 1pt ; ) ; draw r ; \stopusableMPgraphic \defineoverlay[NumberHead][\uniqueMPgraphic{NumberHead}] \def\processMPheadnumber#1% {\setMPtext{chapter}{\bf#1} \useMPgraphic{NumberHead}} \unexpanded\def\HeadTitle#1#2% {\framed [frame=off, bottomframe=on, width=broad, align={broad,nothyphenated,left}] {#1\blank[nowhite]#2}} \determineheadnumber[chapter] \setuphead [chapter] [command=\HeadTitle, headstyle=\ss, numbercommand=\processMPheadnumber{\currentheadnumber}] \starttext \startchapter [title={Fist chapter}] \input knuth \stopchapter \startchapter [title={Second chapter}] \input knuth \stopchapter \startchapter [title={Third chapter}] \input knuth \stopchapter \stoptext 2016-07-09 11:32 GMT+02:00 Wolfgang Schuster :

You need

\determineheadnumber[chapter]

before you can access the value with

\currentheadnumber

- the chapter number appears in black

You need this setup:

\setuphead [chapter] [numbercommand=\Headed]

In the first example, so I do not need the command \currentheadnumber but just do:

\setuphead [chapter] [command=\HeadTitle, headstyle=\ss, numbercommand=\Headed] ConTeXt passes the section number to the argument of the \Headed command. But in this second example, using the command \determineheadnumber[chapter], the chapter number is always 0 You need \determineheadnumber[...] each time when the value for \currentheadnumber should change. \setuppagenumbering[location=footer]

\startusableMPgraphic{NumberHead} picture r ; r := image ( graphictext \MPstring{chapter} scaled 4pt withfillcolor \MPcolor{lightgray} withpen pencircle scaled 1pt ; ) ; draw r ; \stopusableMPgraphic

\defineoverlay[NumberHead][\uniqueMPgraphic{NumberHead}]

\def\processMPheadnumber#1% {\setMPtext{chapter}{\bf#1} \useMPgraphic{NumberHead}}

\setuphead [chapter] [command=\HeadTitle, headstyle=\ss, numbercommand=\processMPheadnumber{\currentheadnumber}] The following works here.

\startusableMPgraphic{NumberHead} picture r ; r := image ( graphictext "\bf\namedheadnumber{chapter}" scaled 4pt withfillcolor \MPcolor{lightgray} withpen pencircle scaled 1pt ; ) ; draw r ; \stopusableMPgraphic \def\processMPheadnumber#1% {\useMPgraphic{NumberHead}} \setuphead [chapter] [command=\HeadTitle, headstyle=\ss, numbercommand=\processMPheadnumber] Wolfgang
