Dear all, I have two questions. 1. I defined \Myheader and use it to shape the chapter head as following: \def\Myheader#1#2{% \framedtext [width=\overlaywidth, height=9\bodyfontsize, background=color, backgroundcolor=lightgray, offset=2pt, strut=no, frame=off, align={middle, middle}] { {\tfb 제 #1 장} \blank[big] {\sans #2} }} \startsectionblockenvironment[bodypart] \setupheadertexts[][{\tfx COUNTING}] \setuppagenumber[number=1] \setuppagenumbering[alternative={singlesided,doublesided},location={footer,right}] \setuphead[chapter][command=\Myheader,before={\dontleavehmode\blank[2*big]},after={\blank[5*big]}, page=right] \stopsectionblockenvironment …. \chapter{The Addition Principle \crlf {\tfx Sum Rule}} …. But it produces an error which is … ! Argument of \Myheader has an extra }. system > tex > error on line 94 in file SumRule.tex … What is wrong in this code? 2. I used "funnyFrame" defined in the MetaFun book. It works fine except that it is left aligned. I'd like to put such a frame in the middle. But \startalignment[middle] didn't work. Is there any way to make FunnyFrame center aligned? Thank you for the reading. Best regards, Dalyoung
