Felipe,

Where you have:

pre_page.search(XPATH_TO_FIRST_LINK_RESULT_PAGE) do |result|
@last_page = WWW::Mechanize::Page::Link.new(result,@@mech, at pre_page).click

You should have:

pre_page.search(XPATH_TO_FIRST_LINK_RESULT_PAGE).each do |result|
@last_page = WWW::Mechanize::Page::Link.new(result,@@mech,pre_page).click


Notice the .each and the removal of an @. Worked for me.

Matt
