thanks, @sunray. noted that I need to add the graphic chart to future post. Snapshot of string info was already in this post. as to machine translation, yes, I fully understood that it's not always accurate, this is why I always checked it to make sure that it's right. Reason why I kept multistore tree as my current translation is because i can't simply translate the words referencing to word itself but what it means in previous paragraph. As to the 代理佣金，it's Chinese meaning of overrides. I know it has another meaning of rewrite etc, but in this string, I personally think it makes more sense to translate it as current one. Pls correct me if am wrong. thanks,
