[Rails] Re: Struggling to delete posts... Can you help?

Sorry forgot to say that in the view that line is inside an iterator:

<% for post in @posts %>
<%= link_to image_tag("cross.png"), post, :confirm => 'Are you
sure?', :method => :delete, :title => "Delete this post" %>
<% end %>

where @posts is set by:
@posts = Post.all
in the PostsController#index method.
