Hi Sylvain,

Indeed, \setupfooterexts is much clearer for page numbering. Thanks for the help!.

Btw, do you know whether there is any difference between \lastpagenumber and \lastuserpagenumber mentioned both by Wolfgang and by the excursion book?
 

I never used you approach with \setuppagenubering (all being said).

This might help,
