The Filter Builder for specifying Context Criteria and Status Criteria opens with a blank “Sheet:1” tab. At the top, the sheet contains a Use ASL Script checkbox and a list box that lists Context objects or Status objects. For expression filters, you select a class from the object menu and then click the plus sign to add attributes that your expression matches against. When using the Filter Builder for Context and Status Criteria, you can use either an expression filter or an ASL filter, but not both. In addition, you cannot add more sheets.
