anyone can help me…? thanks…

Can you share your ‘sections/work/articles’ blueprint? The answer may be there.

type: pages
headline: Notes
parent: site.find("work")
info: "{{ page.dateFormatted }}"
template: projects-article
empty: No notes yet

like this…

Maybe then a setting in the projects-article blueprint? The ‘num’ option?

wow thanks!!!
