	Debug.Log(selectedUnit);

	Debug.Log(System.Int32.Parse("123")); // this work

if (GUI.tooltip != “” )
{
selectedUnit = System.Int32.Parse(GUI.tooltip);
Debug.Log(“test” + selectedUnit);
}
You don’t want to set a nonexistent value. Check to make sure that GUI.tooltip actually is a valid value and if it is, then set selectedUnit to it.
