Need help with Jumping and climbing for player

Hi all, I am new to c# and unity. Im trying to have my player run and jump and maintain that speed and the player doesn't seem to jump while I hold the run button. also when the player is touching the rope it doest stay attached. Some help would be nice. here is the code:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;



public class Player : MonoBehaviour

{

    //Ground logic

    public bool groundTouch;

    public Transform GroundCheck;

    public LayerMask groundLayerMask;



    //Wall logic

    public bool wallTouch;

    public Transform WallCheck;

    public LayerMask wallLayerMask;



    //Rope logic

    public bool ropeTouch;

    public Transform RopeCheck;

    public LayerMask ropeLayerMask;





    //player attributes

    public bool canDoubleJump;



    //rigidbody

    private Rigidbody2D rb;



    //walking

    public float speed = 50f;

    public float maxSpeed = 3;



    //running

    public float runSpeed = 100f;

    public float maxRunSpeed = 5;



    //jumping

    public float jumpPower = 200f;



    //climbing

    public float climbSpeed = 10f;

    public float swingSpeed = 10f;



    //direction

    public bool facingRight;





    //Interactive objects

    private Rigidbody2D rope;



    void Start()

    {



        //Initialize rigidbodies

        rb = gameObject.GetComponent<Rigidbody2D>();

        rope = GameObject.FindGameObjectWithTag("Rope").GetComponent<Rigidbody2D>();



        

    }



    void Update()

    {



        float h = Input.GetAxis("Horizontal");

        float v = Input.GetAxis("Vertical");



        //check if player is touching something

        groundTouch = Physics2D.OverlapCircle(GroundCheck.position, 0.1f, groundLayerMask);

        wallTouch = Physics2D.OverlapCircle(WallCheck.position, 0.1f, wallLayerMask);

        ropeTouch = Physics2D.OverlapCircle(RopeCheck.position, 0.1f, ropeLayerMask);



        //turning left and right

        if (Input.GetAxis("Horizontal") < 0)

        {

            transform.localScale = new Vector3(-1, 1, 1);

            facingRight = false;

        }

        if (Input.GetAxis("Horizontal") > 0)

        {

            transform.localScale = new Vector3(1, 1, 1);

            facingRight = true;

        }





        //Jumping

        if (Input.GetButtonDown("Jump"))

        {

            if (groundTouch)

            { 

                rb.AddForce(Vector2.up * jumpPower);

                canDoubleJump = true;

            }

            else

            {

                if (canDoubleJump)

                {

                    canDoubleJump = false;

                    rb.velocity = new Vector2(rb.velocity.x, 0);

                    rb.AddForce(Vector2.up * jumpPower);

                }

            }



        }



        //climbing 

        if (RopeCheck)

        {



            //player to grab rope when touching it automatically

            //horizontal axis h to swing back and forth

            //vertical axis v to climb up and down 

            //jump off 

            if (ropeTouch)

            {

                Vector2 localPos = transform.localPosition;

                localPos.x = 0;

                rb.gravityScale = 0;

                rb.AddForce((Vector2.right * swingSpeed) * h);

                rb.AddForce((Vector2.up) * v);



            }

            else

            {

                rb.gravityScale = 1;

            }



        }

        



    }



    void FixedUpdate()

    {

        float h = Input.GetAxis("Horizontal");

        float v = Input.GetAxis("Vertical");





        //move player  and control air movement

        if (groundTouch)

        {

            //walking

            rb.AddForce((Vector2.right * speed) * h);



            //running

            if(Input.GetKey("h") && Input.GetKey("d"))

            {

                rb.AddForce((Vector2.right * runSpeed));



            }

            else if(Input.GetKey("h") && Input.GetKey("a"))

            {

                rb.AddForce((-Vector2.right * runSpeed));

            }



        }







        //limit speed

        if (rb.velocity.x > maxSpeed)

        {

            rb.velocity = new Vector2(maxSpeed, rb.velocity.y);

        }



        if (rb.velocity.x < -maxSpeed)

        {

            rb.velocity = new Vector2(-maxSpeed, rb.velocity.y);

        }



        //limit runSpeed

        if (rb.velocity.x > maxRunSpeed)

        {

            rb.velocity = new Vector2(maxRunSpeed, rb.velocity.y);

        }



        if (rb.velocity.x < -maxRunSpeed)

        {

            rb.velocity = new Vector2(-maxRunSpeed, rb.velocity.y);

Hi and welcome. For following posts, please use the code tags to post code. It's the <> button, and there is also a sticky explaining how to use them if you need examples.
As for your problem, i can highly recommend the tutorial series by Sebastian Lague on the topic of character controllers, cameras and so on. He does what you want, in that his character can run, jump (maintain speed while jumping), play the correct animation, being controlled by the camera and so on. The most appropritate episode for your problem would be:
