Field Description
Page Name Optional. Identify a page that is the source of properties referenced on the Constraints tab.

Optionally, add a row with the keyword Top as the page name, to identify a top-level page. The Top keyword allows you to use the syntax Top.propertyref to identify properties, on other tabs of this rule form.

Class Optional. Select the class of that page.
Locate Page Expression The Locate Page Expression option is not supported. Use a data page instead. Rules created in previous versions that use the Locate Page Expression display this field. New rules do not display this field. Changes to a rule that uses this option cannot be saved unless Locate Page Expression is replaced by supported functionality.
Locate Page Activity The Locate Page Activity option is not supported. Use a data page instead. Rules created in previous versions that use the Locate Page Activity display this field. New rules do not display this field. Changes to a rule that uses this option cannot be saved unless Locate Page Activity is replaced by supported functionality.
Page Context Data
Page Context Optional. Leave this blank if the constrained property or properties (on the Constraints tab) all have mode Single Value.

Otherwise, identify a Page List or Page Group property on the clipboard. You can supply literal index (subscript) values or property-reference index values. Precede the property reference with a period.

To indicate that all the values of the index are acceptable, omit any index between parentheses. For example, these are acceptable:

Invoices.py Orders(2).pyItems("Manuals").pyItems Invoices.py Orders().pyItems().pyItemNames
Page Class Optional. If the Page Context field is not blank, identify the class of the page or pages that are identified in the Page Context field. (You cannot use the $ANY, $NONE or $CLASS keywords here.)
