You probably didn't ask in the right box. After you go to Ask Fun Trivia, there's one place for searching the database to see if your question has already been asked. That is the very visible box in the centre of the screen. It says Search Question Database: to the left, and has a button marked Ask Question on its right. Using that will only show you any previous answers to that question. If you don't see your question already asked, you can then click the link that says Can't find your answer? Click here to ask our community and you will be taken back to the first screen. There you will see a link on the right side of the screen that says Post a Question. That is the one you use to actually ask a new question.
