Problem: Graticules do not display in the layout
The graticule grid does not display in the layout after the grid properties have been defined.
No coordinate system has been defined for the data frame.
Solution or Workaround
Define the coordinate system for the data frame. See the "Specifying a coordinate system" section of the book "Using ArcMap," and the ArcGIS Desktop Help topic "coordinate systems" for information on specifying a coordinate system.
