Trouble with scripting the movement of my 2D blend tree

Unity Engine

I created a 2D blend tree that blends a forward and backward walk animation with a left and right sidestep animation. It works in the preview window but it’s not working in-game. Here is a screen of the blend tree:

Here is my current script:

public class PlayerControllerScript : MonoBehaviour {

	Animator anim;
	
	// Use this for initialization
	void Start () {
		
		anim = GetComponent<Animator>();
		
	}
	
	// Update is called once per frame
	void Update () {
		
		float move = Input.GetAxis("Vertical");
		float sidestep = Input.GetAxis("Horizontal");
		anim.SetFloat("Speed", move);
		anim.SetFloat("Direction", sidestep);
		
	}
}

In the Animator, Speed and Direction are increasing and decreasing correctly with the right input but my character is not moving. Is there a problem with my script, my blend tree, or both?

I’ve been looking at some other examples, trying to get a better understanding.

If VelocityX (horizontal movement) and VelocityZ (vertical movement) are the two parameters in my 2D blend tree, I have to calculate these two parameters and apply them to horizontal and vertical inputs? Am I getting close to understanding this?
