I have little idea what this error means.

The error is "Can't add script behavior VisualContainerAssets. The script needs to derive from monobehavior!". I tried Google-ing it and my search didn't do me any good. My search was brief however. I decided that I'd have a better chance for positive results if I just posted about my error. My picture tells of my troubles: The top image is what I'm trying to do and the bottom image is the error is my computer throwing back at me.

The image is covering my learning attempt at 13:32 of this tutorial. Any ideas?

 

The class name inside you script is "NewBehaviourScript", however your script name is "GuessTheNumberGame"

The main class inside your script needs to have the same name as the script name.

 

How silly of me. Thanks for your help!
