Hi all,
I have a counter in an itemize environment which I need to increment by using
\incrementcounter[NameOfTheCounter]
However this does not work in the following example, maybe due to the use of blocks, or some other reason.
I define two blocks, one for exercises, one for the solutions.
Then in each exercise I have a certain number of questions, presented with an itemgroup named Questions.
Analogously I have an itemgroup named Answers, which appear in the solution to an exercise. Now my problem is that some questions don’t have an answer included (for instance they are too easy…) and I need to increment the counter by saying
\incrementcounter[Answers]
But this does not work, for an unknown reason. (See below)
Can anyone give an advice?
Thanks in advance.
Best regards: OK

This doesn’t work because the name of the counter is “itemgroup:Answers”
and you have to use \incrementcounter[itemgroup:Answers] to increase
the counter for the items.

Hi Wolfgang,
Thanks for your answer which solves the problem I encountered.
However the block mechanism seems to have some limitations regarding how a certain block is absent (for instance when the whole solution to a problem is absent).
In another thread I’ll be more precise regarding what I think is missing in the block mechanism: Hans talked about a « coupling » mechanism in mkiv, but I don’t know whether this is already done or not.
In my opinion, what we need is a coupling mechanism which couples for instance each exercise with its hint, and its solution, with a built-in interaction and when for instance a hint or a solution is not there, one does not need to increment manually a counter.
Best regards: OK
