Object reference not set to an instance of an object.

So i'm getting this error message when i'm trying to move my player from another script.

Code (CSharp):

1.     public void Roll1 ()
2.     {
3.         int Dice1 = Random.Range(1, 6);
4.         int Dice2 = Random.Range(1, 6);
5.         int DiceTotal = Dice1 + Dice2;
6.         Playerr.transform.Translate(DiceTotal, 0, 0);
7.     }
8.     GameObject Playerr;

 

Do you have a value assigned to Playerr?

That's what your error means, nothing is assigned to the variable.
