In the Book Format script line, the output type property is set to Sections and one of the sections rules refers to a signature number which is greater than the number of signatures set in the Signatures property.
You will not be able to preview or generate a diary for the current script until this error is addressed.
Solution
•Modify the list of Physical Sections (recommended): Opens the physical sections property editor and lets you either delete the duplicate section, or define other rules for it.
•Change to Standard Flow: Changes the setting of the output type property from sections to standard, thus making the physical sections irrelevant.
