Why won't it run

So the problem is when I press D and S it moves across the horizontal line which is what I wanted, but I assigned a parameter to the character so when I am going over a speed of 0.1 the walking cycle starts and when I go over 3, the running cycle starts. How do I make this happen.
Here’s my code.

var runSpeed : float = 10;
var moveSpeed : float = 3;
var walkingSpeed : float = 0.1;
var golemAnimator : Animator;

function Update () 
	var input = Input.GetAxis("Horizontal");
if(input < walkingSpeed || input > walkingSpeed)
    runSpeed = input*moveSpeed*Time.deltaTime;
    transform.position.x += runSpeed;
    golemAnimator.SetFloat("Running Speed", runSpeed);

This line is wrong - it’s getting executed whatever (well, unless input is exactly equal to walkingSpeed, which, given they’re both floats is an unreliable test) :

if(input < walkingSpeed || input > walkingSpeed)

It’s a bit hard to see the logic of what you’re trying to achieve without seeing your animator (how does “Running Speed” affect your state transitions/blend tree?), but you might find this video useful: Unity 4.0 - Mecanim Animation Tutorial - YouTube
