Subject: Re: Question: A method for summing several variables

Harry,

The natural way to handlie this kind of problem in Ruby would be to
store the form field values in a two-dimensional array, rather than as
specially-named variables. That way, you can use the built-in
iteration functionality that Ruby arrays support to loop through
fields, total them, etc.

I'd recommend looking at the "Containers, Blocks, and Iterators"
chapter of the Pickaxe book
(http://rubycentral.com/book/tut_containers.html) to see how this kind
of object collection is handled in "idiomatic" Ruby code.

If you need more specific help, just let us know.
