Option at Designer screen
With forms (like despatch notes or invoices) totals and subtotals are often required in the design. To do this use the Properties to select the correct type of data and make sure the correct field (one with a total) is chosen.
Not all data types provide totals
Notes
In many situations the form may extend to more than 1 page - the program automatically ensures that any TOTAL items only occur on the final page.
Information boxes that are of type "numeric (total)" allow totalling and specifying the amount of decimal places.
