Hallo! I'll try asking my question a little bit different: With \setupnumber[formula] [number=davidsnumber] the origin formulanumber(what is its name?) will be overwritten and replaced by davidsnumber. But with \setupnumber[figure] [number=davidsnumber] the origin figurenumbering remains untouched and davidsnumber gets an additionl counter. So there are the following questions: - Why is this different behaviour? - How can I replace the figurecounter by davidsnumber such, that captions and figuretables will use this new counter? - Are the origin formula/figure-counters compatible with counters defined by \definenumber? Or are they other animals? Wolfgang
