Hi everybody In my survey there are existing trees and new trees. In the Schema I created a 1:N entity for the new trees. For all new trees an ID should be generated automatically. I tried it with "math:max(parent()/tree/tree_id) + 1". If I then try to add several trees (+ symbol) I get the error message "Circular dependency found in graph". How can I fix this error? Is it possible that the ID of the new trees starts at 100 (101, 102...)? Can a calculated field no longer be used as key? Thanks for your help, Sabrina
