My save function saves the wrong values!!

Thanks in advance. My save/load script is attached to game master object/prefab which travels between scenes , the load function works ,however my save function only saves the base values of my object.

e.g if i set my game master's prefab Armour and Credits value are set to 6 and 20 then the script only ever saves those values and never the updated values of Armour and Credits(I can see the updated values in the inspector when I play). What could be the root of this mystery?

 public class SaveLoad : MonoBehaviour {
 
     public static SaveLoad control;
 
     public float Armour;
     public int Credits;
     public Text Score;
 
 
 
     void Awake(){
         if (control == null) {
             control = this;
             DontDestroyOnLoad (gameObject);
         } else if (control != this) {
             Destroy(gameObject);
         }
     }
 
     void Update(){
 
         if (Score == null) {
             Debug.Log("No Score Counter!!");
         }
         
     control.Score.text ="Credits: " +Credits.ToString();
 
 
     }
