This InDesign processing message occurs when a diary is generated using InDesign and a command is encountered requiring the application of a master page name to the current output page, but that master page name cannot be found as supplied by the FormatText macro function.
As always, when using the FormatText macro function, make sure that the names of fonts, colors, layers, styles, master pages, ...., are spelled exactly as they appear in the InDesign user interface, including any upper and lowercase variation.
