Hi Douglas you have an issue in your syntax - the term is nth with a (h) not ntd with a (d) as below:

/* This is incorrect
#gallery li:ntd-child(3n+1) { clear: left; }
*/

#gallery li:nth-child(3n+1) { clear: left; }

Hope this helps.

There's a typo in nth-child. You've spelled it ntd-child :) Hope this helps!

Still coming up with error for the objective...

@media screen and (min-width: 480px) {

#gallery li { width: 28.3333%; }

#gallery li:nth-child(3n+1) { clear: left; } }

This is because to pass the challenge you need to use the pseudo nth-child selector with the value (4n) rather than the (3n+1) - its an error in the challenge and it rectified with the (3n+1) in the teachers notes for the course.

Great! Thanks Sam and Per, it was because of 3n+1 not being 4n. Challenge error as you said. Have a good day!
