I'm Stumped...

I'm completely lost. I triple checked my code. Am I overlooking something?

app.js
//Select select box
var navigationSelect = document.getElementById("nav");

//Navigate to URL when select box is changed
var navigateToValue = function() {
  window.location = this.value;
}

//Send analytics data
var sendAnalytics = function() {
  //Placeholder  
}

navigationSelect.addEventListener("change") = navigateToValue;
navigationSelect.addEventListener("change") = sendAnalytics;
index.html
<!DOCTYPE html>
<html>
  <body>
    <select id="nav">
      <option value="index.html">Home</option>
      <option value="about.html">About</option>
    </select>
    <h1>Home</h1>
    <script src="app.js"></script>
  </body>
</html>
about.html
<!DOCTYPE html>
<html>
  <body>
    <select id="nav">
      <option value="index.html">Home</option>
      <option value="about.html">About</option>
    </select>
    <h1>About</h1>
    <script src="app.js"></script>
  </body>
</html>

Pretty close, you're missing the actual listener part of the addEventListener method. In this example the listeners are the functions given.

target.addEventListener(type, listener);

Yep, just need to correct the addEvenetListener. See here.
