Paulo,
I had a look at your
examples at the link below and they were very helpful in getting most of the
way there. The final point I now need is to get the third textfield to
total the other two textfield values. I have included a modified version
of your ‘text_fields’ example below to give you an idea of what I’m
after.
The only reference I
have found in regards to being able to perform calculations is the
addCalculationOrder() method, which allows me to state the order the fields
that are calculated, but not the ability to specify the formula that I need
within the third textfield.
I hope this
information helps with stating exactly what I’m trying to achieve with itext
and thanks in advance for all your help.
Regards, Greg.

fields is a world in itself. See the examples in itextpdf.sf.net and if that's
not enought detail your requirements.
