If dragging items in the Script Outline isn’t working, one of the following conditions may be preventing reordering:
The script is page locked.
You don’t have permission to edit the script.
The script is in the Trash.
The script is marked as Limited.
Change-tracking is enabled.
In Variety scripts, Show Brackets is enabled.
Once these conditions have been resolved, you’ll be able to drag Scene Headings (Screenplay) or Slugs (Variety) to reorder your script.
