1) i have an event time (time field) and a travel time (number field, hours) I want to deduct the travel time from the event time to get the departure time


2) i have a self relation from event to event on start time and want to show other events in portal but avoid the event in the screen
      in pict below Barnum Festival should not show in portal, only the 'Test activity'

     hide {EVENTS::kp_events=EVENTS_Event_SameDay::kp_events} makes all 3 field invisible but still shows the blank row


          how can I hide the row?
