I would like to set an existing PDF form field value depending on another form field value. E.g.
if the user who fills the form enters 20 in field A, then insert into field B the value 40 (2*A).
I would appreciate it, if someone has a short example.
FYI: I generate the PDF using QuickPDF and Delphi but this doesnt change anything in the answer I am looking for..
Thanks in advance!
