How do I use Cross Platform Input Manger?

I am working on a 2D Platformer and I am tring to add mobile controls

I am trying to make it so when you touch on the joystick the player will start shooting

I tried to change all of the input.getAxsis with CrossPlatformInputManger.getAxsis but all it did was make me not able to shoot. I also changed the build setting to IOS and made sure mobile input is enabled

If someone could infrom me on what I am doind wrong that would be great!!

Here is the code

void Update ()
{
if (fireRate == 0)
{
if (CrossPlatformInputManager.GetButtonDown("Fire1"))
{
Shoot();
}
}
else
{
if (CrossPlatformInputManager.GetButton ("Fire1") && Time.time > timeToFire)
{
timeToFire = Time.time + 1 / fireRate;
Shoot();
}
}
}

And the Shoot method

void Shoot ()
{
Vector2 joyStickPosition = new Vector2(Camera.main.ScreenToWorldPoint(CrossPlatformInputManager.mousePosition).x, Camera.main.ScreenToWorldPoint(CrossPlatformInputManager.mousePosition).y);
Vector2 firePointPosition = new Vector2 (firePoint.position.x, firePoint.position.y);
RaycastHit2D hit = Physics2D.Raycast (firePointPosition, joyStickPosition-firePointPosition, 100, whatToHit);

Debug.DrawLine(firePointPosition, (joyStickPosition - firePointPosition)*100, Color.cyan);
if (hit.collider != null)
{
Debug.DrawLine(firePointPosition, hit.point, Color.red);
Enemy enemy = hit.collider.GetComponent<Enemy>();
if (enemy != null)
{
enemy.DamageEnemy(Damage);
//Debug.Log("We hit " + hit.collider.name + "and did " + Damage + "damage");
}
}
