Simple enough. However a user can accidentally select the cell, hit space, and it becomes a custom value that no longer changes if the opening is resized. Ideally these should be locked so there's confidence the values are correct. Alternatively, is there a way to schedule which values are 'Default' and which are 'Custom' so the errors can be found and corrected?</T></DIV> Wed, 29 May 2019 05:58:22 GMT Lachlan Green 2019-05-29T05:58:22Z https://community.graphisoft.com/t5/Collaboration-with-other/Locking-Expressions/m-p/228560#M29295 <DIV class="actalk-migrated-content"><T>Hi all,<BR /> <BR /> Is it possible to lock the value of a property expression and prevent custom values? <BR /> <BR /> I've set up a property to show the Height and Width of openings which is then shown in a schedule.
