I can't get past the identical() challenge..

I understand they don't wish for the identical function to execute since the two variables are not equal, so I added the strict operator but it still doesn't work and I'm not sure why.

<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Variables</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
    <script src="ignore_this.js"></script>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Variables: Null and Undefined</h2>

    <div id="container">
    </div>

    <script>

        var myUndefinedVariable =;
        var myNullVariable = null;

        if(myNullVariable === myUndefinedVariable) {
            identical();
        }

    </script>
  </body>
</html>

The line:

var myUndefinedVariable =;

is not a valid assignment. I think in the challenge it just has this;

var myUndefinedVariable;

The difference is the equal sign. If you have an equal (assignment operator) you need to have a valid expression on the right side.
