What's wrong with this? - adding a Community

[ronman]

Just to get something simple working, I wired up a form submit to create a new Community for an existing Container.

Using a similar form, Get Container works, returns info about the Container.

But the following gives a "Perhaps you're missing a required parameter" error.  I've also tried it with all the location parameters, city/sate/zip, lat/lon, zip.  Same error.

I've also tried it with a cURL call instead of a form submit, and as a JQuery ajax call.  All give the same error.

I double checked the key value, but it's not giving an authentication error, anyway.

Oh, and I tried putting all the params on the URL:  ...?key=12345&container_id=1234...etc.

Here's the code:

 <form action="https://api.meetup.com/ew/community" method="POST">

   <input type='hidden' name="key" value="<my key value>">

   <input type='hidden' name="sign" value="true">

   <input type='hidden' name="container_id" value="<my container ID>">

   <input type='hidden' name="zip" value="87506">

   <input type='submit' value='Submit' />

  </form>
