Hi
For the root url, you need to specify the url of an existing form. The easiest way to do this is to copy and paste the url from a Form Variable Definition.
The only output variable you need (despite the *'s) is the output document, which should be a document variable.
The documentation is quite accurate and helpful - but you need to read it carefully.
