This page tests whether you have the Ambulant browser plugin installed for your current browser. If the Ambulant Welcome document is playing back, below: everything is fine.
If you are running Internet Explorer and you don't have the plugin installed yet: you should get a dialog, or possibly an information bar at the top of this window, asking you for permission to install the plugin.
If you are running another browser and don't have the plugin installed yet you will see a link to the install page.
