Hopefully you own the database because it REALLY stinks, you are making joins on text fields which you have not validated on the entry. It also seems like you have no referential integrity in your database other than user input.

In other words you have created a disaster in your database. As Dave said you need to go back to the beginning and redesign your database so it conforms to proper data structures. This site may help you Data Models[^] but I suspect you need to get a book and start learning, it cannot be done via forum posts.
