i now have access to the airship and i need to go to the bevelle temple to get the secret item for the Anima aeon. when i go to the high bridge someone says the gates to bevelle are closed. Can someone tell me how to get into the bevelle temple?

You can't go back into Bevelle BUT... you DID enable to trigger Treasure Box to get the Anima Aeon. So don't worry about Bevelle, you already got the treasure box opened.

thanks =).... now all i gotta do is figure out which one i DID miss

It's easy, if you want to know which one you missed, check out the signs. Match the sign that you are missing to the temple that you still need to do and you're there.
