wont let me put .shift inside .push

I am trying to do task one by using the line shipping.push(orderQueue.shift()); but it comes up with an error. I have done the same thing and testing it out in the console and it works fine in the console. Just won't pass on here.

script.js 
var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = [];

shipping.push(orderQueue.shift());

Hi Scott,

try this:

var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = [];
shipping = orderQueue.shift(0);
