Forms draw their information from either a single table or a single query, but only one.
Forms can do calculations, or can be used to report calculations from queries. However, you cannot enter new numbers in those calculation areas. The form only lets you change the underlying raw data. Suppose a query is based on a table, and a form is based on the query. If you change information on the form, the information from the form is passed back to the query, and the query passes the information back to the table.
