Accumulative fields progressively accumulate data from other fields on
a FormTrap document. Typical use is to accumulate running totals of
data from detail lines such as line amounts. Data is accumulated at the
time of printing the original field, hence is a detail field prints
more than once (two-up invoices for example), two versions of the data
field MUST be defined, with one name used for a single accumulation.
The page elements Report
header and footer, Page header and footer,
Carry forward, and Brought
forward have the access to the accumulative field.
Your document can have any number of
accumulative fields. The Report header, Page
header and Brought forward
page elements will print the value of the accumulative field from the
completed previous page. The Page footer,
Report footer and Carry
forward page elements will print the value of the
accumulative field as it stands upon completion of the current page.
