Change Chart Page Count

[mardicar]

I am creating Descendant charts for inclusion in a Reunion Book. Most of the charts have two pages with a page break. For use in ReunionBook these two pages are counted as one page with a 1/1 in the bottom of the left panel. One of my charts reads 1/2 and comes out half the size of the others when inserted into the book. How do I adjust the page count of that chart to 1/1? I open these in Preview to create pdf's.

Thanks. Mardi
