Code Challenge: Hoisting

Task: Alter the 'elevatorCloseButton' function to follow the best practices in declaring variables within the scope of the function. (Code Below)

I keep getting stuck with declaring 'status'

<!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) {

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

    }

    elevatorCloseButton(true);

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

declare 'var status;' before the if block and remove 'var' from within the if block.
