I am trying to use the AutoFiller with a pdf that has several fields in it that have been copied with Adobe Acrobat Professional. The originally tried the AutoFiller with only one set of fields, but then I created multiple copies of the fields and the AutoFiller doesn't work anymore. Also, after copying the fields in Adob Pro the fields show up with numbers after their names. For instance, the field 'GrossDistribution' is now 'GrossDistribution.0.0.0.0' and 'GrossDistribution.0.0.0.1' and 'GrossDistribution.0.0.0.2'. I've attached the PDF so that you can see. It seems that Adobe is using some sort of array notation in the names. I have read your wiki article on Adobe field names and I have even opened the PDF in notepad to look and see what the field names really are. In notepad the field name shows up as just 'GrossDistribution'. It does look like they have it arranged hierarchal though. It seems like the autofiller should handle this since they are all the same field name.
