If it ends in html it's a webpage address, and you want to put it in the first URL box "Optional Link URL:" and make sure to fill in a title in the next box, or it won't work. The address is given in the box at the top of your web browser, and ends in .html. The title can be any (short) phrase you want it to be, it doesn't even have to relate to the site's contents.
