2D:I have a movementController script on my character but it doesn't move forward

I have a movement controller script on my character but my character doesn't move forward or flip around like it is supposed to. My character has a rigidbody applied as well as a box collider around the body and a circle collider around the feet. This is the code I have applied:

 using UnityEngine;
 using System.Collections;
 
 public class MovementController : MonoBehaviour 
 {
     public float maxSpeed = 10.0f;
     bool facingRight = true;
     
     Animator anim;
     
     
     // Use this for initialization
     void Start () 
     {
         anim = GetComponent<Animator>();
     }
 
     // Update is called once per frame
     void FixedUpdate () 
     {
         float move = Input.GetAxis("Horizontal");
         anim.SetFloat("Speed", Mathf.Abs (move));
         rigidbody2D.velocity = new Vector2(move * maxSpeed, rigidbody2D.velocity.x);
         
         if(move > 0 && !facingRight)
         {
             FlipFacing();
         }
         else if(move < 0 && facingRight)
         {
             FlipFacing();
         }
     }
     
     void FlipFacing()
     {
         facingRight = !facingRight;
         Vector3 charScale = transform.localScale;
         charScale.x *= -1;
         transform.localScale = charScale;
     }
 }
