Hello Everyone, i am not sure if its possible but if it is, i know you guys will know
Datasource 1: Staff
Gallery: galStaff
PeoplePicker Field Name (single selection): Staff
Datasource 2: Reservations
NestedGallery: galReservations
PeoplePicker Field Name (Multiple selection): Participants
i want to show only those reservations in the nested gallery where the Staff name is in the Participant field (multi select person field)

when i have side by side galleries it will work with this formula, (separate page), for some reason it will no work with the nested table above.
Filter(Reservations,galStaff.Selected.Staff.DisplayName in Participants.Value)
