Next, add one array inside the coordinates array. The new nested array should contain two number values.

What am I doing wrong?

script.js 
const coordinates = [
['21','32']
];

Hi Ashley -

You are very close. The challenge is asking you to assign to numbers to the nested array. Since you are surrounding the numbers with single quotes, you are assigning a string, not a number. Take the single quotes off and you'll pass the challenge.

const coordinates = [
[21,32]
];
