I believe that I am assigning the "rainbow" ID, but what this is asking of me that I'm not getting correct?

I have used the 'document.querySelectorAll(rainbow) line to read through all of the list items in the unordered list, but for some reason I keep getting an error that says, "undefined is not part of the function".

index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Rainbow!</title>
  </head>
  <body>
    <ul id="rainbow">
      <li>This should be red</li>
      <li>This should be orange</li>
      <li>This should be yellow</li>
      <li>This should be green</li>
      <li>This should be blue</li>
      <li>This should be indigo</li>
      <li>This should be violet</li>
    </ul>
    <script src="js/app.js"></script>
  </body>
</html>
js/app.js 
let listItems = document.querySelcectorAll(rainbow);
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

for(var i = 0; i < colors.length; i ++) {
  listItems[i].style.color = colors[i];    
}

I've fixed the typo in "querySelectorAll" but I'm still receiving the error.

Yea, when I found it the other day. It was so small, I couldn't see because I was on my phone, using the app. Thanks. >.<
