Issues With Jade Extends

Using Jade for the first time in a project. Pretty great so far. It seems that I am having some issues with the Extends functionality. My block is not showing up when layout.jade renders.

layout.jade:

div.ui.tab.contact(data-tab="contact")
  div.tab-con
    block form

index.jade

extends layout

block form
  h1 Get in touch...

App Configurations:

app.set('views', './views');
app.set('view engine', 'jade');

The route:

app.get('/', index.index);

And index.js with the route export:

exports.index = function(req, res) {
    res.render('layout', {});
}

I would be more than happy to post any other code. Any suggestions would be appreciated.
