I'll let someone else answer to about if how you're doing it is OK, because I'm not really following what you're doing.

However, you don't need saved queries for all your forms, the ones you do have should be properly named yes. If it's a query you're going to use a lot then sure make a query for it, and at the beginner level just make a query for everything. But once you get later on in the courses and start to learn SQL, you don't always need to make a query for everything. It will save you some clutter if instead of making a query to limit criteria you can instead just type right into the record source something like Select * From CustomerT Where CustomerID=1 or whatever situation you were making a query for. Queries are just a pretty way to make SQL statements, if you go to the view button on a query you've made and pick SQL view, you can see the SQL that makes up that query, and if you wanted to, you could just copy that text and paste it into your record source

Then delete your query, although I wouldn't suggest doing that until you are further along. Just some information for you for later :)

What are the odds? I just covered that in Access Expert level 3, video 1 SQL Primer.
