here:

# You want the following code block to return a string each time;
# it'll map to an array of strings, which you join at the end into one 
string:
cgi.params.map {|key, val|
     # cgi.print immediately outputs what you pass it, rather than
     # adding it to the string. just stick a string in there:
     key + "  :" +
     cgi.text_field(key, val.to_s) +
     cgi.br
}.join + # and join the result before moving on
cgi.submit("Okey Dokey?")

And that should do what you want. Everything is a string; the #title 
and #text_field are just shortcuts for creating the html tags. They 
always take strings and return strings.
