Changes

Your page needs to include the JS Prototype library. Currently, automatic inclusion of the Prototype library isn't working, so you'll need to include a <script> line to do so. You can link to the prototype library in Umlaut, see example below.  You will first then include an Umlaut javascript file, and then call the embedUmlaut() js function it supplies. You'll need to pass some arguments to embedUmlaut. :
