HI @SportsMasochist !
Welcome to the forum!
The reason why you are having issues is because you did not fork the project properly.
If you look at the url, it has freecodecamp’s name in it
https://codepen.io/freeCodeCamp/pen/MJjpwO
The url needs to have your username in it.
The fork option is located at the bottom right hand corner of codepen.
Click that option.
Check to make sure the url has your username in it.
Save the project.
Then submit.
Hope that helps!
