Question Steam VR Error With Action Set

NullReferenceException: Object reference not set to an instance of an object
Valve.VR.SteamVR_Action_Boolean.GetState (Valve.VR.SteamVR_Input_Sources inputSource) (at Assets/SteamVR/Input/SteamVR_Action_Boolean.cs:94)
VRController.CalculateMovement () (at Assets/Scripts/VRController.cs:58)
VRController.Update () (at Assets/Scripts/VRController.cs:35)

That's the error I get when I try to run my game.

It seems to be linking lines from my controller input script:

Any Help With this issue is appreciated!
