Increment of public variable not working

Questions & Answers
1

To keep things simple i have a public variable which i increment in the update function, to over time increase the speed of a game object but my debug messages show the value to increase once and no more to 10.4, repeating themselves every update. I believe this should be simple coding but i cannot get it to work, here is my code

using UnityEngine;
using System.Collections;

public class SpeedControl : MonoBehaviour {
    public float speedy;
	// Use this for initialization
	void Start () {
        speedy = 10;
    }
	
	// Update is called once per frame
	void Update () {
        speedy = speedy + 0.4f;
        Debug.Log(speedy);
    }

I hope you can work out to solve this solution as i have spent ages fiddling around in hope it will work.
Thanks,

The initial value is 10, then you add 0.4 and you say it only reaches 10.4. I think you are setting the value = 10 from another script.
