Unity C# text not changing

Question

I have a text box that fades in and out and changes colour depending on the animation, this works well enough, but the text doesn't change when i tell it to. I tried some other Stack answers, but they didn't work. Below is the script that contains the code that SHOULD change the text. I have been on this for ages and my brain hurts, mostly because of the animation (parameters and transitions mostly).

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

using UnityEngine.UI;

public class Objectives : MonoBehaviour {
#region Variables
public bool CompletedAnim1;
public bool StonesFallen;
public bool IceFallen;
public Objective ObjectiveRef;
public Text PlankText;
public AnimController AnimContRef;
public TextController TextContRef;
string NewText;
#endregion Variables

// Use this for initialization
void Start () {
    CompletedAnim1 = false;
    NewText = "Drop All Ice";
    PlankText.SetAllDirty();
}

// Update is called once per frame
void Update () {
    if (StonesFallen)
        ObjectiveRef.ObjectiveCompleted = true;

    if (StonesFallen && IceFallen)
    {
        PlankText.text = "Drop All Ice";
        ObjectiveRef.ObjectiveCompleted = false;
        AnimContRef.SetTriggerParameter("FadeIn");
        Debug.Log("Ice and Stones Fallen");
    }

    if (CompletedAnim1)
    {
        PlankText.text = NewText;
        Debug.Log("CompletedAnim1");
        Debug.Log(PlankText.text);
        PlankText.SetAllDirty();
    }
}


}

Answer 1

You assign a string to PlankText.text twice in all the script, once inside if (StonesFallen && IceFallen) and once inside if (CompletedAnim1) .

Problem is that you always assign to it the string "Drop All Ice" , the first time using the string, and the second time using NewText , which contains the same string.

And it can't be that NewText changes its value outside the script, because it's private , unless you cut out part of the class in your post.
