Error Already =/

Hey everyone,

I just installed Unity 3D and I’m following a tutorial. I’m trying to use the standard FPS options that was already installed in Unity. I’m having trouble, I’m getting this error. Help?

NullReferenceException: Object reference not set to an instance of an object
FirstPersonControl.Update () (at Assets/Standard Assets (Mobile)/Scripts/FirstPersonControl.js:66)

You forgot to set a variable in the inspector for the gameObject that you’ve attached the FirstPersonControl.js script to. In the future, please use search.

How do I set a “variable” in the inspector?

Can you send me a link on how to do that? I just installed Unity 3D yesterday and have no idea about any of the terminology that you’re using.
