trouble with run animations

im using unity 2018.3.6
Iv created an avatar using UMA and written a script from a YouTube tutorial to make character click to walk.I must be missing something here.

Here are images of animator, error and also script.
any help much appreciated!!!

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

public class ClickToMove : MonoBehaviour
{
    private Animator mAnimator;

    private NavMeshAgent mNavMeshAgent;

    private bool mRunning = false;
    // Start is called before the first frame update
    void Start()
    {
        mAnimator = GetComponent<Animator>();
        mNavMeshAgent = GetComponent<NavMeshAgent>();
    }

    // Update is called once per frame
    void Update()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

        RaycastHit hit;

        if (Input.GetMouseButtonDown(0))
        {
            if (Physics.Raycast(ray, out hit, 100))
            {
                mNavMeshAgent.destination = hit.point;
            }
        }

        if (mNavMeshAgent.remainingDistance < mNavMeshAgent.stoppingDistance)
        {
            mRunning = false;
        }
        else;
        {
            mRunning = true;
        }

        mAnimator.SetBool("running", mRunning);
      
    }
}

I assume the script “ClickToMove” is attached to the same gameobject where the animator component with the “running” parameter is attached to, right?

If that is the case, make sure your script and scene is saved (in case you made currently changes to your variable names). If this doesn’t help too, try out writing “running” with an capitalized “R” in your script like the warning says.
