Ciao, Roberto,
ecco la parte inglese del forum.
Per favore scrivi l'inglese o scrivi nella parte italiana.
But as I understand your question:
You would like to randomly display some questions of a group one by one.
This is how I would solve it:
In each group randomly create a string of Y characters (Y number of questions in the group) like "0110010010".
Something like {join(rand(0,1),rand(0,1)...)}
To display only questions with value "1" use something like "substr(mystring,1,1)=='1'", "substr(mystring,2,1)=='1'", ...
Regards
Joffm
