How to make a telephrase game on Habbo?

Ok so I have the effects and triggers all good but there is still one thing I have to establish. How on earth do you make it so that only the people in the playing areas answer actually work? I have set the room up into 4 different areas. Right near the door we have where people come in and wait for the next game, then we have the playing area, then where I will sit and then there is where the players get teleported to. They are all separated by dividers. At the moment I can say the answer anywhere and I will get teleported to where the players get teleported to. But I want to make is so that only people in the playing area can say it. How do you do this?
