calculate in forms

["Haseloff, Lutz" <Lutz.Haseloff@mdf.brandenburg.de>]

Hi all, Hi Hans,

I want to prepare a form with calculating fields.
My file looks like this:
.....
\startJScode{Format}
AFNumber_Format(2, 3, 0, 0, "", true);
\stopJScode
\startJScode{Keystroke}
AFNumber_Keystroke(2, 3, 0, 0, "", true);
\stopJScode
\startJScode{Calculate}
AFSimple_Calculate("SUM", new Array ("Summand1", "Summand2"));
\stopJScode
.......%%% I use the Scripts from AForm.js because my JS programming is poor
\setupfield
  [ErgSetup]

[frame=on,width=8cm,height=4ex,format=JS(Format),afterkey=JS(Keystroke),calc
ulate=JS(Calculate)]
........
\hbox to 11cm{Summand 2:\hfill  \field[Summand2]}

\hbox to 11cm{Ergebnis :\hfill  \field[Ergebnis]}
...........

All scripts are at the right places in the pdf-file (tested with Acrobat)
and the format and afterkey
scripts work very fine.
Only the calculation does not work.

Is it possible that the missing  "/CO [...]" near /Fields is the Reason?
In the PDF Specification the "Calculate Order" is required.

Greetings

Lutz
