You'll need to concatenate the various strings together to get this to 
work.  You might also consider using instance_eval to simplify things.

#!/usr/bin/ruby -w
require 'cgi'
cgi = CGI.new("html3")

ary = %w( one two three )

cgi.instance_eval do
    out do
        html do
            head do
                title { "Form Test" }
            end +
            body do
                form do
                    ary.collect do |value|
                        text_field value, value
                    end.join + submit
                end
            end
        end
    end
end
