It is  my previous question refined:

Code below creates pdf form with 3 fields, which are numerical, and
the third field is the sum of two first. However if I open it in
Acrobat (or Reader) the third field is not calculated. But if I open
in Acrobat and use Form > TextField tool I see that it should be
calculated; if I click to pick up the fields to have their sum
calculated, I see that the correct fields are checked. If I close
field selection dialog and then exit  TextField tool without doing
nothing, the third field is calculated.

My question: how I should modify the source to have calculation really
enabled without trick I described? Another question: How to calculate
more complicated expression (still in frames of "Simplified Field

Thank you in advance
