Subject: n00b ? re: CGI Hash and arrays

Hi, n00b here, and got myself stumped on something I thought was easy.

I get CGI params returned as:

params: {"conf_mod"=>["20"], "conf_impact"=>["10"],
"avail_impact"=>["5"], "integrity_impact"=>["5"],
"authorization"=>["5"], "integrity_mod"=>["5"]}

I just want to add up the values in the hash keys.  Seems simple, but an
hour or so later, after trying numerous things no go.  Any help
appreciated.

#!/usr/bin/ruby

require "cgi"

cgi = CGI.new('html4')
values = cgi.params
#values.each_value { |y| total += (eval y.join('+'))  }
#values.each_value { |x| total += x[0] }
#values.each_value do |v| puts v end
#cgi.header
cgi.out() do
    cgi.html() do
      cgi.head{ cgi.title{"TITLE"} } +
      cgi.body() do
        cgi.pre() do
          CGI::escapeHTML(
            "params: " + cgi.params.inspect + "\n"
           "total: " + puts(total) + "\n"
          )
        end
      end
    end
end
