When errors in project data are reported in the Notifications panel, the Description field typically indicates an action must be taken to resolve the error: “Value must be specified”. An unresolved error can be severe enough to cause a prescriptive calculation to issue a failure report.

Double clicking on the error opens Room Type Manager, selects the room type listed in the Notifications panel Object column, and highlights the property listed in the Notifications panel Field column.

You can set the value to resolve the notification error.
