Very new to this an need help

 
I am supposed to put the following in my html page 
  1. <link rel = "stylesheet" href = "jquery-ui.min.css" >
  2. <script src="external/jquery/jquery.js"></script>
  3. <script src="jquery-ui.min.js"></script>

I am supposed to find this in the index.html page however 
all I can find is the stylesheet?

Anyone know what I could be missing?

Thanks,
