Hi Victoria Hsieh,

There’s nothing extra that you have to do for this challenge. The issue you’re running into has to do with the method you’re calling on the document object. You’ve spelled it incorrectly, and so it’s not working the way you’re thinking it is. It’s an easy syntax error/mistake to make.

Here’s a link to an article on Mozilla Developer Network:

https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementById

If you’re not able to spot the error on your own, let me know and I’ll tell you.
