I have tried the challenge but I still don't get it how to solve it. Any ideas?

To follow best practices, you shouldn't declare variables inside an if block. So you need to declare the variable status inside the function, but before the if block, then simply modify the variable inside the if block.

function elevatorCloseButton(pushed) {
    // Declare the variable here, instead of inside the if block
    var status;
    if (pushed) {
        // Modify the variable here, instead of declaring it
        status = "I'll close when I'm ready.";
    }
}
