MissingMethodException: Method not found- Error on fps script

I started making an FPS game 2 days ago using tutorials on the internet and I have a problem with some of my code. This script was shown on a tutorial but when I used it I got an error In-Game. This is the code.

var cameraObject : GameObject;
@HideInInspector
var targetXRotation : float;
@HideInInspector
var targetYRotation : float;
@HideInInspector
var targetXRotationV : float;
@HideInInspector
var targetYRotationV : float;

var rotateSpeed : float = 0.3;

var holdHeight : float = -0.5;
var holdSide : float = 0.5;  


function Update () 
{
	transform.position = cameraObject.transform.position + (Quaternion.Euler(0,targetYRotation,0) * Vector3(holdSide, holdHeight, 0));
	
	targetXRotation = Mathf.SmoothDamp( targetXRotation, cameraObject.GetComponant(MouseLookScript).xRotation, targetXRotationV, rotateSpeed);
	targetYRotation = Mathf.SmoothDamp( targetYRotation, cameraObject.GetComponant(MouseLookScript).yRotation, targetYRotationV, rotateSpeed);
	
	transform.rotation = Quaternion.Euler(targetXRotation, targetYRotation, 0);
}

The script seems to work because my gun follows the mouse in-game, but i get this error multiple times in my console when i play.

MissingMethodException: Method not found: 'UnityEngine.GameObject.GetComponant'.

If anyone needs more evidence to help fix this then ask and I will post. Please answer ASAP!

“GetComponant” - should be spelled “GetComponent”
