Hello evrybody!

I need in a Toc pagenumberings with romannumrals and numbers.

I have written this one:

\mainlanguage[de]

\setupinteraction[state=start] % don't forget this line!

% make chapter, section bookmarks visible when opening document

\placebookmarks[chapter,section,subsection][chapter,section]

\setupinteractionscreen[option=bookmark]\starttext

\setuplist[chapter]

\setuplist[section][width=1em]

\setuplist[subsection][width=1.5em, margin=0.6em]

\setuplist[subject][margin=1.5em]

\setuppagenumbering

\setupcombinedlist[content][list={part,chapter,section,subsection,subsubsection}]

\setupuserpagenumbering[conversion=romannumerals]

\setupinteraction

  [state=start,

   style=,

   color=,

   contrastcolor=]

\setuplist

  [chapter]

  [after={\blank[line]}]

\setupcombinedlist

  [content]

  [aligntitle=yes,

   alternative=c,

  interaction=all]

\setuphead [part]

        [sectionresetset=,

         conversion=Romannumerals,

         placehead=yes,

         bodypartlabel=chapter]

\setuphead [chapter]

        [sectionresetset=,

         conversion=,

         number=no,

         placehead=yes,

         bodypartlabel=part,

         sectionsegments=chater:chapter]

\setuphead [section]

        [sectionsegments=section:section]

\starttext

\placecontent

\startpart

   [title={Danksagung}]

\startchapter

   [title={Bildbeschreibung der Cover-Grafik}]

\startchapter

  [title={Einleitung:"Entwicklung" behindern?}]

\startsection

  [title=Activité 2]

\startchapter

   [title={Cours-Méthodes}]

\startsection

  [title={Coordonnées d'un point dans un repère}]

\startsection

  [title={Coordonnées du milieu d'un segment}]

\startchapter

   [title={S'entraîner}]

\startsection

  [title={Coordonnées d'un point dans un repère}]

\startsection

  [title={Coordonnées du milieu d'un segment}]

\stoptext

The mistake is ,that i have writen after compiling comes: error in line 13: \setupuserpagenumbering[conversion=romannumerals]
