How Do I get the Blog Tab to work?

i am testing this to see how i will appear on my blog.  I am very confused about this blogging thing.

 

I see the blog tab on the top of the page but cannot get it to work when I click on it…no reaction

 

When Iclick the buttons on the main page of my webpage, the buttons that lead me to the blog, send me to the comingsoon page

I am lost

setting up this blog truly feels like rocket sign and an impossible task to accomplish
