Forms allow you to easily see the data for each field, as well as quickly switch between records or create new ones. Forms are essential for extended periods of data entry, as most people find them much easier to work with than tables. This will create a form based on the fields contained in the table automatically. Access does a pretty good job of automatically creating fields that are the correct size, but you can resize and move around any elements on the form that you want. If you don't want a specific field to be displayed on the form, you can right-click on it and select Delete. If your tables have relationships, a datasheet will appear beneath each record, showing the connected data. You can edit your connected data this way much easier. For example, each sales rep in your database may have a customer database attached to their record. The arrow buttons at the bottom move from record to record. The fields will be populated by your record data as you switch between them. You can use the buttons on the edges to move to the first or last record. This is located in the upper-left corner, and will allow you to start changing the values of your table by using the form. You can edit the text in any field of each record to change the data in the table. The changes will reflect automatically in the table, as well as in any connected tables. Click the "Add Record" button near the navigation buttons to create a new record at the end of the list. You can then use the fields to input data into the blank record in the table. This is a much easier way to add new information than through the table view. Make sure to save your form by pressing Ctrl + S so that you can easily access it again later. It will appear in your navigation frame on the left side of the screen.
Select the table that you want to create a form for. Click the Form button in the Create tab. Navigate your new form. Click the datasheet button to use the table. Make changes to existing records. Add new records. Save the form when finished.
