Can't See Mobile Single Stick Control

Hello,
I am trying to use the mobile single stick control from the unity standard assets. Unfortunately, even though I have the prefab in my scene, I cannot see the controller. I have attached two pictures. The first picture if of what the inspector shows of my joystick and the second picture shows where the joystick is but that the sprite is missing.
Thank you,
Ninnec

So the problem was that I did not have the mobilejoystick prefab checked in
