Hi, I created a participants table with the 5th attribute as "12345co89"
Activated the survey "not anonymous".
Then I get as "gruppoa" -> "CO"
and in the dropdown there are only the items with codes starting with "CO"
and a second with attribute "12345az89"
So it seems to work. I hope I understood correctly.
This seems to be really strange.
Hopefully Tony can investigate further.
All the best
