[NTG-context] problem with counters (page)

My efforts to set up a new page counter in the footertexts of a book are not proving successful. The following code shows the nature of the problem. \definecounter[volpage][type=page, way=bypage] \starttext \setcounter[volpage][5] \dorecurse{3}{\startTEXpage[offset=2pc] \input ward \blank[medium] \centerline{\red\tfa\rawcounter[volpage]\incrementcounter[volpage]} \stopTEXpage} \stoptext As you will see, the counter is not incremented on pages 2 and 3. I expect that I have missed something important. But what? Alan
