    This action cannot be performed because the field is not modifiable error message

    samjs

      I've created at Student database and on the layout I've created a portal to display all zipcodes and cities from another table to be able to edit or add new ones. When trying to add a new city, I get the error message,

      This action cannot be performed because the field is not modifiable error message.

       

      • My relationship is based on 2 calculation fields with the word "key".
      • My relationship allows to add and delete records.
      • I can place my curser in the field and type in it but when I exit the field I get the error message.

       

      I've never experienced this error when creating a "key" relationship. I'm using Filemaker 12.

      Any help would be greatly appreciated.
