Im new to Unity and I was using a tutorial to make a 2d platformer. Everything was going well until I tried to add jumping and crouching. For some reason I get this error when trying to run the game.

UnityException: Input Axis Veritcal is not setup.
To change the input settings use: Edit -> Project Settings -> Input
playerControls.Update () (at Assets/2D Mario Assets/Scripts/playerControls.js:66)


Im not sure why this happens but even when I go into input settings and try to change it, it still doesn't work.
It only seems to jump when pressing the left or right arrow keys(which is to move left and right) while pressing the jump keys.
Any idea on why this is happening?

Okay I put it up. All i tried to do was change the jump button to up and the vertical inputs were up and down.

I've been tinkering around with the code and its seems that the problem has to do with this code:
if (velocity.x ==0 && Input.GetAxis("Veritcal")

is there a reason that affects the jumping?

Typo? "Veritcal" > "Vertical"

your right Im sorry I thought it was correct
