ArgumentException: Input Axis horizontal is not setup.

ArgumentException: Input Axis horizontal is not setup. To change the input settings use: Edit -> Project Settings -> Input PlayerMovement.Update () (at Assets/How to Make a Video Game/Assets/Scripts/PlayerMovement.cs:29)

I have seen other answers and they do not help. Could my script be wrong?

Axis are case sensitive. You need a capital letter at the start, "Horizontal" not "horizontal".

Also, not all problems can be solved this easily. We would very much like if you could post your code next time you have an issue.

Cheers.
