Why is my Unity Mathf.Lerp not working?

Question

I'm trying to make a moving platform and I've set up a script that handles the lerp of the platform, but no matter what I do I can't get the darn thing to move. The method I set up is supposed to lerp a float which will be the x-axis of the transform.

 

using UnityEngine;

using System.Collections.Generic;

using System.Collections;

public class PlatformController : MonoBehaviour

{

float Output = 0;

float CurrentXPos;

void Start()

{

CurrentXPos = transform.position.x;

}

void Update()

{

Vector3 temp = new Vector3(PlatformMovement(), transform.position.y, transform.position.z);

transform.position = temp;

Debug.Log(Output);

}

float PlatformMovement()

{

float accumulator = .001f;

Output = Mathf.Lerp(CurrentXPos, 8f, accumulator);

accumulator += .05f; //Constant speed

return Output;

}

}
