Switching Overlay Scenes with Python

Game Engine Game Engine Support and Discussion

I’m attempting to write a Python script to do just that, but my knowledge of BGE python is not very developed and I would appreciate anyone’s help if it takes me in the right direction.
This is my script at present:

####################  Set scene

# get controller
controller = GameLogic.getCurrentController()

#
senList = controller.sensors

# get sensor
One = senList["One"]

# get actuator attached to the controller named switchScene
act = controller.actuators["switchScene"]

# set scene name
act.scene = "overlay"

Also here is my .blend
