Unity 3D character movement

Question

I've created a character in Unity. I prepare to walking, turning and running an animation. I created three scripts for this character.

I want to when I clicked, button my character have a movement with this animation. When I clicked up button character use walking animation going forward. My down, left and right button isn't working:

#pragma strict

internal var animator:Animator;

var v:float;
var h:float;
var sprint :float;

function Start ()
{

    animator=GetComponent(Animator);

}

function Update ()
{

    v=Input.GetAxis("Vertical");
    h=Input.GetAxis("Horizontal");
    //Sprinting();
}

function FixedUpdate()
{
    animator.SetFloat("walk",v);
    animator.SetFloat("Turn",h);
    animator.SetFloat("Sprint",sprint);
}

function Sprinting()
{
    if(Input.GetButton("Fire1"))
    {
        sprint=0.2;
    }
    else
    {
        sprint=0.0;
    }
}

function MoveUp() { v = 1.0; }
function MoveDown() { v = -1.0; }
function MoveLeft() { h = -1.0; }
function MoveRight() { h = 1.0; }

This question might get better answers on gamedevelopment SE — FullyHumanProgrammer
before you repost it on gamedev.stackexchange.com as @FullyHumanProgrammer mentioned you should try to fix your indentation as the current code is hard to read. — Minzkraut
I started trying to fix the indentation and remove some of the many duplicated blank lines but I gave up because there was just far too much code. If it's too much code for me to just deal with whitespace, think about how somebody you want to answer your question feels! — Wai Ha Lee

You might wanna use the animator's Blendtree and use a direction and a speed variable to define which animation to play. This Unity tutorial will help you: https://unity3d.com/learn/tutorials/modules/beginner/animation/blend-trees?playlist=17099

Good luck ;)
