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

console.log(status);

elevatorCloseButton(true);

The code they are looking for is this:
function elevatorCloseButton(pushed) {
var status;
if (pushed) {
status = "I'll close when I'm ready.";
}
}
Even though the code would function the same with the var keyword inside the if statement (the way it is when you start the challenge), it's a best practice to define all the variables that you're going to use inside the function at the top - even before you've used them.
It makes it easier to the read code if you can see all the variables that are going to be in play in the function right at the top.
