First thanks to everyone who responded. Secondly, apologies for popping up to ask a question and then not responding sooner.. had only intermittent access over the Canadian Thanksgiving weekend. Thirdly, an extra ++ to Roger for providing a working re-write. After seeing the first couple responses, I had begun to think (again, had only limited access to actually play on the weekend) of how I could maybe use the get_token method, but wasn't sure - you provided some proof.

Thanks again to everyone!
