Works for me (minus comment signs of course): ConTeXt ver: 2024.03.11 09:34 LMTX Best wishes, Taco

If anyone can fix it, thanka very much

You have to add a check to ensure there is a value stored in the aux-file before you pass the value to the counter. This is necessary because when you process the document for the first time Context only saves the value and can access it only in the next run after. %%%% begin example \definedataset [myset] \starttext \setdataset [myset] [foo=1,boo=4] \doifelsesomething{\datasetvariable{myset}{1}{boo}} {\scratchcounter\datasetvariable{myset}{1}{boo}} {\scratchcounter\zerocount} boo = \number\scratchcounter \stoptext %%%% end example Wolfgang

I must have made a mistake with something, I changed a counter and it somehow worked properly. Because I've designed too many counters, I still haven't figured out exactly what the problem is doing. But admittedly, the question I asked is non-existent. It's a problem with my design.
