I7 : Problem of association

Hello everybody,
I have a little problem. This is my code :

Wroom is a thing. Understand "salle d[']eau" as wroom. The problem is that an error caused by the “[’]”. If I delete the [ ], the error disapears but when the player write salle d’eau, it doesn’t work. Does someone have an idea for me ?

Works fine with me without the brackets.

[code]There is a room. Wroom is here. Understand “salle d’eau” as wroom.

Test me with “x salle d’eau”.[/code]
