[NTG-context] Thumbnail sample.

The wiki shows two thumbnail samples. I like the
first one. But I want to use MKIV. When I do the
first sample blows up on the second chapter entry.
Obviously there is some code in sample 1 that
doesn't work  under MKIV. 
By a process of elimination it centers on the
thumbnail description proper. The file looks
like this:
\def\rawsectionnumber#1{\countervalue{\??se#1}}%will be in kernel





\def\NOfChapters{4} % i need to make this one available

\startsetups thumbs


     \vbox to \paperheight \bgroup
         \vskip \rawsectionnumber{section-2}
     \measure{thumbheight} \vskip
     \doifoddpageelse\hfill\donothing \framed
     [background=color, backgroundcolor=darkgray,
             {\bfa \rawsectionnumber{section-2}}



\chapter{first}  \dorecurse{10}{\input tufte  }
\chapter{second} \dorecurse{10}{\input davis  }
\chapter{third}  \dorecurse{10}{\input zapf   }
\chapter{fourth} \dorecurse{10}{\input bryson }


It works under MKII but not under MKIV. The error
message occurs after the first chapter. But the
chapters by themselves work OK. 
I will continue to experiment----
