Prim Counter with llGetParcelPrimOwners

Hi everyone

I'm building a prim counter with llGetParcelPrimOwners, but I have some problems with that on group-owned land.

I tried it on several group-owned lands, at some it works, at some not.

Does anyone have an idea, which rights to check for this one?
It was always tested by the land owner and the Script itself was set to the group, that was owning the land.

thanks for reading,

Not sure this is how it was intended to work, but on group-owned land I've found that if owned by somebody in the group with proper perms, the script only works when that person is on-line. But if the scripted object is *deeded* to group, then it seems to work all the time.
