In Excel and Word there are UserForms. Access forms are much more powerful. You should have your Access form bound to a query or table. This is much different that than how a Word/Excel Userform works.
To get the full power of an Access form you will need to set the form's record source so it is bound to a table or query. By doing this Access will automatically save the data to the table and clear the form when you move to a new record. AN Access bound form (set the record source) can Create, Read (display), Update and Delete (CRUD) data in a table without adding any buttons ore VBA code!
