Hey there, please consider: \starttext \defineenumeration[definition][text=Definition, alternative=serried] \setupnumber[definition][way=bysection, numbersection=yes] \section{My section 1} \startdefinition My fist definition \stopdefinition \section{My section 2} \startdefinition My second definition \stopdefinition \stoptext It should number my definitions 1.1 and 2.1, but it doesn't. The prefix is missing. Any ideas? Thank you and best regards, Johann
