I cannot understand what is the error in the code

Assets\GunContoller.cs(20,15): error CS1061: 'Animator' does not contain a definition for 'SerTrigger' and no accessible extension method 'SerTrigger' accepting a first argument of type 'Animator' could be found (are you missing a using directive or an assembly reference?)
Please help me

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GunContoller : MonoBehaviour
{

Animator m_animator;
// Start is called before the first frame update
void Start()
{
m_animator = GetComponent<Animator>();
}

// Update is called once per frame
void Update()
{
if (Input.GetMouseButton(0)) {

m_animator.SerTrigger("name");
}
}
}

 

looks like typing error?
see docs:
https://docs.unity3d.com/ScriptReference/Animator.SetTrigger.html

 

There's no "Ser Trigger" in animatorcontroller. You made a typo. Correct spelling is SetTrigger.

 

Thanks i finded
