Hello Martha, You defined the Master Page 'First' only once, probably on a right-handed page. But in your MasterPageMap you defined the use of 'First' two times: one for a left-handed page and one for a right-handed page.
Best practice for a first page is: set the Paragraph tag (in this case 'ChapterTitle) to begin on a right-handed page and in your MasterPageMap only define the Master Page in the column under 'Right-Handed' - set the Page Range Indicator to 'Single'. If you also use left-handed first pages you must define both a left-handed Master Page and a right-handed master Page using different names (f.e. First-L and First-R) Kind regards, vriendelijke groet, Wim Hooghwinkel Adobe Certified Expert (ACE) in FrameMaker iDTP International DTP and Documentation Consultancy tel. +31652036811 info at idtp.eu www.idtp.eu *************************************
