Need help in unit 5 lesson 7


#1

i have done every thing correctly so why will it not work?

this is the code:

 <div class="row">
      <div class="col-md-4">
      <div class="thumbnail">
      <img src="http://goo.gl/0sX3jq" >
    </div>

    <div class="thumbnail">
      <img src="http://goo.gl/an2HXY" >
    </div>
  </div>
      </div>

      <div class="col-md-4">
    <div class="thumbnail">
      <img src="http://goo.gl/Av1pac" >
    </div>
    <div class="thumbnail">
      <img src="http://goo.gl/vw43v1">
    </div>
  </div>
  </div>
</div>

Saying that I am missing a div class

I see multiply problems: You already close your row (div with class row) after your first col (col-md-4), this should be after your third col which i don't see at all
