GUIDED PRACTICE: MODIFY FORMS
In this activity you will follow along with your teacher to add a query-based subform
to a form and make modifications to the form and subform.
You will need the B&B database used earlier in this objective and well as two other
tables that you will create according to the directions below. A query will be created to
gather information for the subform from the Reservations and Prices tables and link it to
the main form.
Part I: Add tables to the B&B database, retrieve data from another table, and set
property values.
1. Open the B&B database and create a database table using the following
information. Save the table as Prices.
Field Name Data Type Description
ID AutoNumber
Inn Lookup
Double Occupancy, Regular Room, 2 Queen
Double Currency
Sized Beds
2. Set the ID field as the primary key
