how come i cant have the same animation activated by different keys???

so i made a walking animation through blender and watched a tutorial on how to import the animation and how to activate it when pressing a key on the keyboard. so i used "W" to play the walking animation and it worked fine i then wanted to to make some more animations for walking right ,walking left , and walking back. but when i used the same method to play an animation as i did for the walking foward my player would just bounce and fly all over...

heres the script....

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class character_animations : MonoBehaviour {
 
     public  Animator anim;
 
     void Start () {
         anim = GetComponent<Animator>(); 
     }
 
     // Update is called once per frame
     void Update() {
 
         //walking left
         if (Input.GetKey(KeyCode.W))
         {
             anim.Play("walking");
         }
         else
         {
             anim.Play("Idle");
         }
 
         //walking right
         if (Input.GetKey(KeyCode.A ))
         {  
             anim.Play("walkingRight");
         }
         else
         {
             anim.Play("Idle");
         }
 
     }
 }

can someone help me? if i was not clear in the question sorry:)
