It says "Alter the 'elevatorCloseButton' function to follow the best practices in declaring variables within the scope of the function."
And I have tried a few times and re listened to the video several times.

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

1,403 Pointsok so 'defining' a variable is just declaring it with nothing after but a semi colon? I understand the principle of hoisting just couldn't work out how to 'define' the variable.
Thank you! :)
