Ahh, okay, I understand what you want now. I thought you wanted readers to find the key first and then knock (and I was guessing use the key if there was no answer).
I’m actually not sure, maybe try placing the word “choice” on a separate line above the choice name.
choice
“Find the key and surprise him.”{
And putting these together:
}}”Knock on the door.”{
}
I don’t think you need that label?
I’m sorry, I don’t know why your code isn’t working but those are the only suggestions I can think of.
