Challenge task 2 of 2! i'm stuck... nth-child pseudo selector

Hi ,I'm stuck , help is very much appreciated !

here is the question:

Now, clear the left side of every 4th list item in the element with the id of "gallery". Here's a hint: You'll need to write another selector inside of the media query at the bottom of the file, in addition to the one you wrote in the previous step. You'll also need to use the nth-child pseudo selector.

But when i try i get this : Bummer! Did you set "clear: left" on every fourth gallery list item?

Where have i made a mistake ?!

css/main.css 
a {
  text-decoration: none;
}

#wrapper {
  max-width: 940px;
  margin: 0 auto;
}

#logo {
  text-align: center;
  margin: 0;
}

h1, h2 {
  color: #fff;
}

nav a {
  color: #fff;
}

nav a:hover {
  color: #32673f;
}

h1 {
  font-family: Changa One, sans-serif;
  font-size: 1.75em;
  font-weight: normal;
}

img {
  max-width: 100%;
}

#gallery {
  margin: 0;
  padding: 0;
  list-style: none;
}

#gallery li {
  float: left;
  width: 45%;
  margin: 2.5%;
  background-color: #f5f5f5;
  color: #bdc3c7;
}

nav ul {
  list-style: none;
  margin: 0 10px;
  padding: 0;
}

nav li {
  display: inline-block;
}

nav a {
  font-weight: 800;
  padding: 15px 10px;
}

.profile-photo {
  display: block;
  margin: 0 auto 30px;
      max-width: 150px;
  border-radius: 100%;
}

.contact-info {
  list-style: none;
  padding: 0;
  margin: 0;
  font-size: 0.9em;
}

.contact-info a {
  display: block;
  min-height: 20px;
  background-repeat: no-repeat;
  background-size: 20px 20px;
  padding: 0 0 0 30px;
  margin: 0 0 10px;
}


@media screen and (min-width: 480px) {
  #gallery li {
  width: 28.3333%;
  }

#gallery li: nth-child(4n) {
  clear: left;
  }
}

HI Ben

Just delete the space after the "li" :

#gallery li:nth-child(4n) {
  clear: left;
  }
