Before modifying a form, you need to know that forms can be viewed several different ways:
Form View: The normal view where you can view, add, and edit records. You can't modify the form's structure in this view.
Layout View: Layout View allows you to apply formatting and rearrange fields while also displaying data.
Design View: Use for in-depth modification and customization of your form. Live data is not visible—you're only working with the structure of the form.
Datasheet, Pivot Table, Pivot Chart: These views are available only for certain types of forms.
Print Preview: Displays a form as it would look when printed, although you'll rarely need to print a form—that's why you have reports.
