At the request of Jess I'll let you know how to do tabs in blogger.
You don't need an html code and all of that (though I did go through that whole process before realizing I was barking up the wrong tree).
On blogger dashboard select "New Post"
This will direct you to the "Posting" tab, with subtabs: new post, edit posts, and edit pages.
Select edit pages.
Create a new page, and voila: that's a new tab.
It's just that simple.
