Hi, the \definelabel command does not work any more in the latest betas. Here's a minimal document: \definelabel[SlideNumber][headstyle=normal,way=bytext] \starttext \incrementSlideNumber \nextSlideNumber \stoptext Works fine with the older version I have here 2009.03.30 18:28 and fails with the latest beta: ! Undefined control sequence. l.5 \incrementSlideNumber \nextSlideNumber All best Thomas
