If you are just gonna write any unwanted comments please then dont respond to this message!I don't know if this qualifies as unwanted or not.
(How would I determine that before posting ????)
in Reply#1 Warnerj did tell you what was wrong and how to fix it,
I'll quote the entire thing for you

public boolean isExpired()You don't have a matching right-brace to end the setAutoExpires method implementation.I know you asked him to show you where the brace was supposed to go but I honestly don't know what else he could have said.
