[EP-tech] Adding file to eprints record using perl script results in "In PDF Document: You need to select a file to be shown first"

[patrik.camilleri at gmail.com (Patrick Camilleri)]

Hi John,

I can't thank you enough! It worked!

The strange thing is that I had previously tried:
  $doc->set_main($filename);

which I assumed is the same thing as
  $doc->set_value("main", $filename);

but that didn't work.

Thanks again,
Patrick
