Basically what I'm trying to do is, that if it's an old session, I want to show the data that was displayed when the session was new. The only time I want new data is if the session is new. I'm trying to use setAttribute when the session is new and getAttribute when the session is old. Would I be able to store and grab array data like this? Thanks
