What am I doing wrong with the addEventListener()?

Can anyone please look my code and tell me what I'm doing wrong with this challenge.

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(click,'change') = navigateToValue ;
navigationSelect.addEventListener (click,'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>

You added the addEventListener but did not format it correctly. Your code should look like this.

navigationSelect.addEventListener('change', navigateToValue);
navigationSelect.addEventListener('change', sendAnalytics);

Syntax

target.addEventListener(type, listener[, useCapture]);

type

A string representing the event type to listen for.

listener

The object that receives a notification when an event of the specified type occurs. This must be an object implementing the EventListener interface, or simply a JavaScript function.
