[NTG-context] page number

Dear Wolfgang, I have a book in preparation with running heads. Pagenumber marking | marking Pagenumber The chapter title page has empty headings. The publisher would like the page number centered on the Chapter title page. I manage to put it there but I don’t want it to run on the following pages. I have made various attempts but can’t manage it. I have \setuplayout[location=doublesided] \setuppagenumbering[location=,alternative=doublesided] \setupheadertexts[chapter][][pagenumber] \setupheadertexts[{\getmarking[chapter]}][pagenumber] Can anyone show me code to achieve this? Thanks, Charlie
