Hello @YeauNamKim
When you say “when you try to submit”, what exactly are you trying to do? Can you please be specific so I can try to help you.
Also, I note that your Maps profile is hidden. Please be aware that this will significantly limit your participation on the Leaderboards and reduce the benefits that you could gain from the T100 System behind them. You can learn more about this by reading the Readme section on each of the Leaderboards posts.
Finally, when you leave a message for me please properly tag me as I have done in this reply to you. You might wish to learn about tagging by reading this tutorial by @MortenCopenhagen.
