Running a parameter query is also easy.
When you (or someone else) runs the query, a dialog box appears with the message that you created (in other words, the text you put between the brackets in the query grid), such as "What region do you want to view sales for?"
When you type in the region and click OK, Access does the rest. It will display results based on what the user types, which in this example is sales by region.
If your query covers a range, such as a start and end dates, you will be prompted to type in the first value, then the second value, and poof, the results appear. More on this in the last lesson.
