Subject: Easy task, Sum array element... Why doesn't it work?

I have done it many times before, but this time I can't get it too work.
I'm starting to get a bit frustrating.
So, I'm trying to sum all elements from the second element in a Array
using inject. The problem is that inject returns nil every time. What am
I doing wrong?

parameters.each {|element| print element + ","} --> ?faq,using,rtorrent
parameters.each {|element| print element.class.to_s + ","} -->
String,String,String
parameters.class --> Array

Doesn't work.
(parameters[1]..parameters[-1]).inject {|result, element| result +
element} --> nil
Neither does.
(parameters[1]..parameters[-1]).to_a.inject {|result, element| result +
element} --> nil
