Controller/Camera STILL falling

I somehow made my Camera or controller fall through the terrain. I have deleted all things that have a camera and when I switch to game mode all I see is grey. I am very new to Unity so thats not helpign much. There was an errror message that said an item had gone out of the play area, it was ignoring it, save and restart and it would be solved. It wasnt. Now Im gertting errors that say,

UnassignedReferenceException: The variable cameraTransform of ‘ThirdPersonCamera’ has not been assigned.
You probably need to assign the cameraTransform variable of the ThirdPersonCamera script in the inspector.
UnityEngine.Transform.get_rotation () (at C:/BuildAgent/work/842f9557127e852/Runtime/ExportGenerated/Editor/UnityEngineTransform.cs:56)

ThirdPersonCamera.Awake () (at Assets/Standard Assets/Character Controllers/Sources/Scripts/ThirdPersonCamera.js:61)

And

Please assign a camera to the ThirdPersonCamera script.
UnityEngine.Debug:Log(Object)
ThirdPersonCamera:Awake() (at Assets/Standard Assets/Character Controllers/Sources/Scripts/ThirdPersonCamera.js:39)

The problem isnt that it fell through, itsw that I cant get my gameview back to normal.

PLEASEA HELP ALL YOU SMART PEOPLE! My assignemnts due tonight!

I am new to Unity, like it says, so a bit more would be great. Drag which part into where in the inspector? I dragged the 3rd person controller with the square icon inot the inspecort window where it would allow. Not sure if that was right or not. I can put a new camera down and it still just shows grey. Also, I was doign final touches when this happened, have been tryign to fix it for hours.
