Adding python tool output to arcmap automatically when analysis is complete

Greeting all...

I've written a python scrip that is run in arctool box given user specified inputs... at this point the tool works but I would like to have the tool automatically
add the resulting output datasets to the ArcMap table of contents.

I've tried a few variation of the following code... keep getting the same error... see below. I think it all goes back to this line of code where its not recognizing which dataset to add to the map. Any help is appreciated.


mxd = arcpy.mapping.MapDocument(r"D:\Risk_Models\Sample_Design\sample_design_tool.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "*")[0]

print "ready to add layer"
print sample_plots

newlayer1 = arcpy.mapping.Layer(r"D:\Risk_Models\Sample_Design\Sample_design_tool\sample_design_tool.gdb\state_GA")
#newlayer2 = arcpy.mapping.Layer(sample_points)

print newlayer1

arcpy.mapping.AddLayer(df, newlayer1, "TOP")
#arcpy.mapping.AddLayer(df, newlayer2, "Bottom")

del mxd, df, newlayer1

end code

Error... reported in python
