I have found an error when the user (HR Rep) submit the PDF after review it.
The error is on Flash Player:
Type error: Error#1085: The element type "string" must be terminated by the matching end-tag "</string>".
at flash.external::ExternalInterface$/_call n()
at <anonymous> ()
Thanks in advance
Make sure to use Internet Explorer and not FireFox.
There's a bug with the Reader Submit with FireFox.
I'm going to flag this as assumed answered.
