Photon Web-connected LED HTML error

I followed the instructions on the tutorials page for the web-connected LED. After making a html file, I am stuck. I get an error {“error”:“invalid_token”,“error_description”:“The access token provided is invalid.”}. I believe the issue is how I am copy pasting the device ID and access token. How does the information specifically get entered? I have it as…

<!1e002100xxxxxxx c7acb5xxxxxxxxxx>

What is the specific format that needs to be replaced between the ? Do the ‘-’ remain?

Could you show us the exact code you’re using? Copy & paste it here (and change some characters of you accesstoken).

Should look something like this:

<!-- Replace your-device-ID-goes-here with your actual device ID
and replace your-access-token-goes-here with your actual access token-->
  <form action="" method="POST">
    Tell your device what to do!<br>
    <input type="radio" name="arg" value="on">Turn the LED on.
    <input type="radio" name="arg" value="off">Turn the LED off.
    <input type="submit" value="Do it!">

I’m pretty sure that leading exclamation mark (!) is not supposed to be there, nor should be the angled brackets (< and >)
