The Dink Network

Your script says Dink should only unfreeze if the choice picked is number 4, so there's a problem. Just remove the

if(result== 4) [<-- missing an &]
{
}

check entirely, and only have unfreeze(1) there.

As for why the bookshelf won't say anything, it's probably your lack of spacing in the if check. Try writing it as

if(&result == 1)

or if it still doesn't work, as

if (&result == 1)

EDIT: You're also missing an underline in choice_start() and choice_end().
