error in block code example

I guess there’s an error in this part of the code:

link_to_function("Show me more", nil, :id => "more_link") do |page|
  page[:details].visual_effect  :toggle_blind
  page[:more_link].replace_html "Show me less"
end

It doesn’t work. It should be:

link_to_function("Show me more", nil, :id => "more_link") do |page|
  page[:details].toggle "Blind"
  page[:more_link].replace_html "Show me less"
end
