Format rules row

Hi everyone
in a “maintenance” table that refers to a “means” table,
I have a status column.
when the “completed” value is entered in the status column, the module is closed.
I would like the form reference line to be formatted in the “means” table

Which one is the parent table? Maintenance or Means?


It could be like IN(“Completed”,[RelatedMaintenance][Status])

thanks a lot!

You’re welcome
