    //Used for CT 
    private float current_CT = 0f;
    private float Max_CT = 100f;
    
   

    // Start is called before the first frame update
    void Start()
    {
        CurrentState = TurnState.PROCESSING;
    }

    // Update is called once per frame
    void Update()
    {
        switch(CurrentState)
        {
            case (TurnState.PROCESSING):
                CTCounter();

                break;

            case (TurnState.ADDTOLIST):

                break;

            case (TurnState.WAITING):

                break;

            case (TurnState.SELECTING):

                break;

            case (TurnState.ACTION):

                break;

            case (TurnState.DEAD):

                break;

        }
    }

    void CTCounter() //Turn count to 100 like FFT
    {
        current_CT = current_CT + Speed;

        float calc_CT = current_CT / Max_CT;

        if(current_CT >= Max_CT)
        {
            CurrentState = TurnState.ADDTOLIST;
        }
    }
}

I am trying use a public int from one class to preform a calculation on the Statemachine but I am having issues for it to see the same int of Speed.

What I have tried:

Tried to create in instances and classs to pull from .this to try to pull the what I need.
