Rails - Oct 2005 - view help

I setup a method in my model to get a rank (it does an avg) and i get
this error when i view the page. what im thinking is even though i use
the as sysrank AR doesnt let me reference it? if not how would i do
this?
thanks

undefined method `sysrank'' for #<Array:0x25890d4>

Extracted source (around line #27):

24:         <% if @myrank = Comment.rank(@system.id) %>
25:         <tr>
26:             <td>
27:              RANK: 1 - 10 <%= @myrank.sysrank %>
28:             </td>
29:         </tr>
30:         <% end %>

model:

class Comment < ActiveRecord::Base
    belongs_to :systems

    def self.rank(id)
        find_by_sql (["SELECT system_id, avg(rank) as sysrank from
comments where system_id=? group by system_id",id])
    end
end


Here is the view snippet:



<% if @myrank = Comment.rank(@system.id) %>
        <tr>
            <td>
             RANK: 1 - 10 <%= @myrank.sysrank %>
            </td>
        </tr>
        <% end %>
