Technology stack problem using codepen

Hello everyone! I finished the pomodoro clock project and I passed all the test in my localhost, but when I uploaded the project on codepen I can’t pass any of them because of a problem with the technology stack. Thank you in advance!

Here is the link to the project: https://codepen.io/Flor95/full/YzybWNG

There is no element with a beep id, so the audio variable is null when you try to access the methods and properties on it.

You don’t seem to have an audio element or sound file at all, maybe you forgot it when transferring the code to Codepen?

Yes, I did forget to include the audio element when I transferred my code. Thank you so much for your help!!! :star_struck: :blush: :blush: :blush: :blush:
