Yea, it's weird. Sometimes "<" works for me and sometimes it doesn't. I
couldn't find this operator documented in the Jinja2 or Ansible docs and I
don't recall where I first learned it so I figured maybe it's an invalid
operator. I put a debug statement right before the line where I'm
referencing server_num and it said it was set as I expected it to be but
the statement still failed.
