Answer 1

Your first script is named "Gird" not "Grid".

Second Script:

public class Testing : MonoBehaviour
{
   public Gird1 gird1; // Assign in the inspector. We need an instance of Gird1

   private void Start()
   {
       if (gird1 == null) { // In case someone forgot to assign in the inspector
           gird1 = (Gird1)FindObjectOfType(typeof(Gird1)); // .. We'll search the scene
       }
       gird1.Gird(20,10); // Call the Gird() function on your gird1 instance
   }
}
