I'm trying to develope a cost per SF or area for a each floor type in a project.
At the properties level of each floor, under the parameter 'Cost', I have tried to add the formular of dollars * area or dollars * SF. Revit give me an error of, only constant expressions are allowed.
Can anyone help me from here?
