Specifying default values for themes (FileMaker Pro Advanced)FileMaker Pro and FileMaker Pro Advanced use default values to replace attributes that are invalid or missing. For each theme listed in a theme file, you can specify whether the default values are determined by the current layout settings, which change when a user changes them, or by standard layout values, which are the same values that FileMaker uses when creating a file for the first time.If you don’t specify a value for the THEMEDEFAULT element in the theme, FileMaker Pro Advanced uses standard layout values by default.
