@TPS,
You are a long way from the form creation stage. Your schema is still unnormalized. If you expend all this effort to create forms and other objects before finishing your foundation, you will be reluctant to fix things later and you'll end up with an app built on quicksand.
Please, do yourself a favor and go back to the drawing board on your tables and get them defined correctly before moving on. Do some reading on normalization and ask questions as you try to move the pieces around.
The big difference between Excel and a Relational Database such as Access is that in Excel, your data is stored as a report so it is dependent on format and frequently duplicated. In a Relational Database, data is stored once and ONLY once and referenced whenever you need to see it. If you are old enough to remember the card catalog that you ran right into when you entered a library, picture that. It was your map to finding stuff. There were three "indexes". Author, subject, Title. What you are doing is you are trying to stuff all the books in each index box. In a relational Database, Data is stored in the most efficient way to eliminate duplication and therefore potential errors but can be displayed and reported on however you want and however it makes sense to the users. How you store the data is absolutely critical to the development of an application. If you make mistakes in this foundation, you will pay the price essentially forever.
