I need help with coming up with the correct code solution. An explanation why would be really helpful too! Thanks.

function elevatorCloseButton(pushed) { status = "blue"

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

}

elevatorCloseButton(true);

</script>

Matthew;

I think his example is around 4:20 in the video.

You need to first declare the variable under the function, then set it under the if statement. 

function buttonToLaunchRocket(pushed) {
    var status
    if (pushed) {
          status = "There she goes!"
    }
}

Hope it helps.
