Start with a form that has two text controls.  Use the labels to indicate
which will hold a start date, and which will hold an end date.

Create a query that returns data you want to see.  Since you are describing
a "date range", one of the fields of data available must be a date field.
Use parameters in the Selection/criterion "cell" under that date field.
Your parameters will look something like:

   Between Forms!YourForm!txtYourStart And Forms!YourForm!txtYourEnd

NOTE -- this approach will only work if the form is open, and the controls
have date values.

One more step -- in design view of the form, add a command button that opens
the query.

When you have this much working, work on the second query using the same
approach.  Rather than add a second command button, consider adding the code
that opens the second query to the first command button.
