Im trying to make a remake of a game i enjoy playing on my mc server but for some reason this skript doesnt work. i added the messages to player so i could see what was going wrong and the variable {roomcodee} skips past all of the other variables even if their contents are the same, which i dont understand. i am just learning skript so it might be a bit messy but please help

i realised that on the second line it says "set {roomcodee} to true" and i fixed it but it still doesnt work
