Can someone please confirm what to enter in the 'Insert Behaviour' field of a batch output config file to append the PDF output to an existing file - according to the instructions in the auto-generated batch control IOK template (and Forum posting):

'End' should work, but it isn't working for me (error message below).

Batch output warning: One or more files could not be published and were skipped:

• Row 1:
  Invalid insert behaviour "end".
