Hi Laurence,
Try the following text mode
displayname=Group Members
listmethod=nested(userGroups).lists
listdelimiter=<br>
textmode=true
type=iterate
valueexpression=IF({user}.{isActive}="true",{user}.{name})
valueformat=HTML
Note that the above will only return the username if their account in Wokfront is active.
Hope this helps!
Best Regards,
Rich.
