Hello Cracks ;-)In the code below I encounter the problem, that I have to define the same xPath function variable $organizations twice and I do not understand why. Running the code with the newest versions of BaseX or with Saxon EE, I get a runtime error when I leave the second definition of $organizations out. Any explanation? Thanks in advance.

Which runtime error do you get? I guess the group by binds your let variable for each country in the group so perhaps head($organizations)($country) would suffice without redefining the variable. It would be an odd way to solve it, I would prefer to have a declare function local:organizations($country) declared before.
