I am sure I am missing the obvious on this. I have a master record (Contract) that can have anywhere from one to five (but no limit really) related records of services to be provided. Each related record has a start date and end date with a status (active or inactive). I want a calculated status on the parent record that swtiches to Inactive when all related records are inactive. I am just not seeing the calculation for this. Currently I have it manually toggled on the related records as well as the master record.
