日本語サイトにあえて英語で質問するのはどういう経緯かは気になる。
StackOverflowとかあるのですけど。

[swanne]

because i believe, Japanese more high quality answer to me.
and i wonder Japanese with conversation.

[m.ts10806]

矛盾がありそうな返答ですね・・・。
仕様としても「世界中から得られる可能性が高い」という点からも
StackOverflow本体のほうがmore high qualityだと私は思います。
teratailよりもスタートが何年も早く、よりシステム的に高いとも思います。

[swanne]

hmm.. okay!
your answer is right.
but i just want help, here and there ^^
could you please help me?

エラーの意味は理解されてますか？
アドバイスをしようにも「エラーの通り」くらいになります。
