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.
I updated it a few times. Try now. With the if condition. Worked perfectly for me.
