Dots are reserved in PDF files for representing "widgets", which are the
various visual representation of the same field.
For example, when you create radio-buttons they all have the same name, but
each button is a widget.
So I would suggest using a different naming scheme for your fields.
Thanks, I was aware of the 'widgets' feature; I was using this to allow me to calculate the sum across several fields.
Sounds like a problem in the field calculation order.
Yeah, I thought that too, but I didn't see any difference when I adjusted them. I'll see if I can try again when I get a chance later, perhaps I messed up the order.
