Velocity not changing value in Blend Tree

So I have this blend tree with a Walking and Jogging animation.

I wrote a code so the velocity increases when "w" is pressed and decreases when released. The velocity increases and decreases on the script (I serialized field to check), but the Velocity on the animator does not change its value. How do i fix this? Here is the code and another photo.

 ![public class AnimationStateController : MonoBehaviour
 {
     public Animator animator;
     [SerializeField]
     float Velocity = 0.0f;
     public float acceleration = 0.1f;
     public float deceleration = 0.5f;
     int VelocityHash;
     
     // Start is called before the first frame update
     void Start()
     {
         //set reference for animator
         animator = gameObject.GetComponent<Animator>();
     }
 
     // Update is called once per frame
     void Update()
     {
         //get key input from player
         bool forwardPressed = Input.GetKey("w");
         bool runPressed = Input.GetKey("left shift");
 
         if (forwardPressed && Velocity < 1.0f)
         {
             Velocity += Time.deltaTime * acceleration;
         }
 
         if (!forwardPressed && Velocity > 0.0f)
         {
             Velocity -= Time.deltaTime * deceleration;
         }
 
         if (!forwardPressed && Velocity < 0.0f)
         {
             Velocity = 0.0f;
         }
         
         animator.SetFloat(VelocityHash, Velocity);
     }
 }
