Jump not working?

Unity Engine
1

I’ve recently started to make a 2D platformer game. I got the character to move around by using the A and D keys, but then when I started to follow some tutorials on how to make the character jump, none of them would work! Here is the code for my current jump program.

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

public class JumpingScript : MonoBehaviour
{
    public float fallMultiplier = 2.5f;
    public float lowJumpMultiplier = 2f;

    Rigidbody2D rb;

    void Awake()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        if (rb.velocity.y < 0)
        {
            rb.velocity += Vector2.up * Physics2D.gravity.y * (fallMultiplier - 1) * Time.deltaTime;
        } else if(rb.velocity.y > 0 && !Input.GetKeyDown(KeyCode.UpArrow))
        {
            rb.velocity += Vector2.up * Physics2D.gravity.y * (lowJumpMultiplier - 1) * Time.deltaTime;
            Debug.Log("it works!");
        }
    }
}

I made the key to jump the up arrow and even made a debug log tester. The tester worked, so whenever I pressed the up arrow it would say “it works!” in the console, but my character would not jump. Any help is greatly appreciated!
