I have data that needs to be entered. It is the same data across 3 tables but only for the first three columns, then it is different. I can create a form for one of these but not for all three.
Your description suggests that you are having some design issues..
Normalization said:
Avoid data redundancy. Ideally, a piece of data should be stored in only one place, so that
its value can never be ambiguous. When a value is needed, refer to the one place where it is stored.
