sorry to bother you again, and thanks for the fast reply!
I saw this: <?php _e('For the "Application Website" and "Default Callback URL" fields, please put in this URL: ','tumblr-importer'); echo '</strong><strong>'.home_url().'<
and i didnt know if I need to visit a page or a page is supposed to pop up, because I didnt know where to put the links, and wasnt sure if the links i entered in the tumblr page were correct (ie in the right boxes XD)?
