accessing object attributes

I have an hash of display names and their corresponding object attribute names called @columns. As I iterate through @columns, what is the syntax for accessing the attribute of the object using c? I get an error on the 4th line.

        <% for c in @columns["object_"+@object.categorie] do %>            <tr>            <td class="name"><%=c.first%></td>            <td><%= @object.c.second %></td>            </tr>

        <% end %>

It's really hard for me to tell what you're trying to do here. How about we simplify and take it from there?

<% @columns.each do |key, value| %>   <%= key %> = <% value %> <% end %>

Now, what is "@object" and how does it relate to the contents of either 'key' or 'value'?

Thanks for your reply! I have figured it out...

it should be

           <td><%= @echantillon[c.second] %></td>
