JavaScript JavaScript Foundations Variables Hoisting

I don't know what I'm missing here, so it's difficult to craft a specific inquiry. Please help.

Please see attached code. I know this is a simple concept: hoisting. I know this means having a variable defined outside the function so that it takes precedence, but I'm missing the syntax somehow, perhaps with how it's written within the function. I've tried several ways, but without success.

index.html 
<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Variables</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Variables: Hoisting</h2>

    <script>

    function elevatorCloseButton(pushed) {
    var status = pushed
        if (pushed) {
      console.log("I'll close when I'm ready.");
        }

    }

    elevatorCloseButton(true);

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

Hi Michael,

You're almost there with that one. Try this:

<script>

    function elevatorCloseButton(pushed) {

        var status;

        if (pushed) {
            status = "I'll close when I'm ready.";
        }

    }

    elevatorCloseButton(true);

</script>

Interesting. So within the function you're ensuring that the variable is present, but without setting it equal to something it becomes malleable, to be redefined with each branch in branching and/or conditional statements.
