i have no idea how to use queries. i need help badly!

Have you tried reading any information in the Help files?

Queries and Tables are for the most part interchangeable. Any place you would use a table, you could use a query (and probably should) instead.

There is not much point in having a database full of information that you cannot use. Queries allow you to use the information you have stored in your tables in the way that is most useful to you. Therefore, think about what you want to see and what order you want to see it in (ie numerically or alphabetically). Once you have mastered this you can then go a whole lot further and get really clever by using more than one table, querying queries and more. They are nothing to be afraid of and you will soon see that they are invaluable.
As with every thing else, just play around and see what you can come up with.
