When using the logic wizard to create an 'Action', if you leave the 'Action Type' as the default 'Set C-Bus State' and change the application to 'Trigger Control', select a 'Group Address' and then change the 'Action Type' to 'Set C-Bus Level', the 'Action Selectors' do not appear. However, if you run through the same process and set the 'Action Type' to 'Set C-Bus Level' before selecting a group address it works fine. :confused:
