The word form and the second instance of the form are being generated by 
the {{=BEAUTIFY(response._vars)}}. How did that get in your view file? Can 
you show the exact code of your controller action and view file? Do you 
have {{=BEAUTIFY(response._vars)}} in your layout.html file?

To my knowledge, the BEAUTIFY line came with the default view file. I 
certainly would not know to type that line.

Is there a configuration setting that I have changed or need to change?

def first():
form = FORM(INPUT(_name='visitor_name', requires=IS_NOT_EMPTY()),
INPUT(_type='submit'))
if form.process().accepted:
session.visitor_name = form.vars.visitor_name
redirect(URL('second'))
return dict(form=form)

{{extend 'layout.html'}}
What is your name?
{{=form}}
{{=BEAUTIFY(response._vars)}}

What do you mean by default view file? The book tutorial instructs you to 
create a /views/default/first.html view file from scratch.

 The from scratch steps I too were from the Admin page Views section. I 
 entered first intot the create file with filename edit control and chose 
 the Create button.

 When I do this in a new application, the resulting first.html file

 {{extend 'layout.html'}}

 {{=BEAUTIFY(response._vars)}}


Yes, that's just a template generated by the admin app. You can delete all 
that and enter your own code. You can also just create a view file from 
scratch using any text editor (no need to use admin).

Note, response._vars is the dictionary returned by the controller function, 
and the BEAUTIFY helper turns lists and dictionaries of objects into HTML. 
So, {{=BEAUTIFY(response._vars)}} is a quick and easy way to display the 
objects returned by the controller without having to really code a view. It 
would typically be used for development purposes during prototyping.
