When a Fields polygon is selected the script zooms to the polygon extent. But, I want to return the AddMessage line if the correct Feature Class is not selected. The script does not get to the else statement for other Feature Classes. But, when another polygon or polyline Feature Class is selected it zooms to full extent, as expected. So, why does the script not use the else statement for Feature Classes other than Fields?
fds = arcpy.mapping.ListLayers(mxd, "Fields", df) for fds in arcpy.mapping.ListLayers(fds): desc = arcpy.Describe(fds) type = desc.shapeType if type == "Polygon": df.extent = fds.getSelectedExtent() else: arcpy.AddMessage("Fields polygon not selected")
