Well, to put in the answer you press the Y button and then you type in the order. you don't enter the answer with the tiles showed in the screenshot. they are just there to help you figure it out.
Joshia, enter digits in the order of ABCDEFGHI. So if your A is 7, B is 8, C is 2, D is 3, E is 1, F is 4, G is 5, H is 6, I is 9, enter 782314569. Not ECDFGHABI. All puzzles require digits.
I'm sorry! I've ever played this game but I've forgot how to answer the question. As L. who has made this game says, you should input nine digit sequence after you press Y button.
Josiah you got it, just reenter your answer as numbers like Hanzo and I said. Let me know if you're stuck anywhere else from now on. And thank you Hanzo! :D
