title: I'm pretty sure I'm suppose this statement
body: <p>OK, I'm kinda stuck on this one. I'm looking in my book. </p>
  
  <p>I'm thinking I'm supposed to use the if or the else statement with this. When I try to validate it is coming up with 3 errors. Can someone point out hints to what I'm missing? </p>
  
  <p>Thank you. I'm not this far in javascript yet.</p>
