Please copy-paste the exact command line and full console output. And I
insist: *exact*, copy-paste: your message hints at a simple typo somewhere,
but it is impossible to guess exactly where.

I do not understand your notation. The concat filter will concatenate all
three video together into a single stream and the all three audio together
into a single stream. That is what "n=3:v=1:a=1" means.
