An error was encountered while creating the x,y event source.
Verify that you have entered the correct parameters for this operation and that the data contained in the X and Y fields is in the correct format. The fields must be numeric to be displayed. For example, if the coordinate value is stored in degrees/minutes/seconds in a field (for example, -120 13 58), you need to convert the values to decimal degrees and store them in a numeric field. In addition, some characters in field names are not supported, such as dashes (for example, x-coord for the field name), spaces, and brackets. Before adding x,y data, you should edit the field names to remove these characters. For example, you can use the underscore character instead of the dash character in field names. For more information, see the Make XY Event Layer tool help.
