Data not saving from form embedded in article

I've created a form which works well from the direct form URL but when I embed it in an article. using the plugin, the form loads correctly om the page but the data doesn't get saved in the database. Is this a bug or have I missed something?

Thanks Calculus. I checked the second of your references and it fixed the problem.
