Reference_Syntax.pageSpan( OBJECT param )
An integer representing the number of logical pages a form object spans. For example, consider an 8-page form with a form object that exists only on pages 2, 4, 5, and 6. In this case, using the pageSpan method on the form object returns a value of 5, which is the number of pages of the form the object spans.
