You got the methods right, but you have brackets around 'orderQueue.pop()' on the last line. Remember that brackets signify an array, so since you want do something rather than define something, you need to stick with a plain method. By using brackets, you're defining 'cancelled' as an array, which isn't what you want to do.

var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = orderQueue.shift();
var cancelled = orderQueue.pop();

Hello Che,

I would simply remove the surrounding square brackets in the var cancelled declaration, the rest looks fine to me.
