Thanks Old Bruce. Will try that on the old file—but have got page numbers! Went new document, set up with the same number of pages, then immediately went to master and added page numbers and that works. Added baseline grid, still have numbers. The old file—followed your instructions; the weird bit is, can only see one master at a time: so, right-click on masterB and get dialogue apply masterA, with B greyed out. Try right-click on B, get A with B greyed out. applied either, no page numbers. So the old file is somehow corrupt? Perhaps, cannot add content and then page numbers? That was what I did . . . will send the file if you think it worthwhile!
