Can't get Frontend list view to work

Hi again Tuan

I've been trying to get the list of those registered for an event to show in the fronten.
I've set the permissions so thatt authers - wo can create an event - can see the list and manage it. That works.

I've also set it so that normal registered users can see the list, but not manage it. That doesn't work at all. Unfortunately this is an important criterium for the client I am testing this for.

In the attachments, I have images which show the settings I am using.

Any ideas?

Regards
David
