Subject: Ruby Hash Querying

Hello,
I am new to Ruby and have run into a small snag. I have a hash like
so:

@documentnames = {
  :finance_whitepaper => 'whitepaper one',
  :ecommerce_whitepaper => 'whitepaper two',
  :integratedsvs_datasheet => 'whitepaper three'
  }



So I am trying to then go like so:

@documentnames[k]

where k is a variable in a loop with the key from the has minus the
":" in front

But if I try to add the ":" in front

<%key = ':' + k%>

And then try to reference the element

<%= @documentnames[key] %>

I get a null value....
