What you want to accomplish is ***REALLY BAD*** database design. I really don't think I can explain what you should do in one post, but for starters you do not want to create fields for specific dates, no matter how many you have. You would accomplish listing reports in date groups by using query or report functions.
Again, I can't really help you here with your request to be honest. Many beginners tend to view Access (or other database) tables in the same way they would an Excel spreadsheet, also known as a "flatfile". My best advice is to look at any of the myriad of Access beginner books and learn the basics.
