nancy, the first (sad) thing that people learn about sorted tables is that they don't exist in Access. The trick is that you can create a query that contains an ORDER BY clause to implement a sort and can then open the QUERY. Just about anything you do with tables you can do with queries. (I DID say "just about"!)
When you create a form, you can make it use the table, or you can give it a query name for a query that contains everything the table contains but with an ORDER BY as part of the query. Your users will NEVER know the difference and the table contents will ALWAYS be shown in whatever order you designed into the query.
As a general rule, you NEVER show a user the navigation elements of the database because you can't trust them. (No, I'm serious.) Their agenda is not your agenda. You want to keep the database clean. They want to do what they need to do as quickly as possible. Those two goals are rarely well-aligned.
One solution is called a "switchboard" form. You can search this forum for many articles on that subject.
