My Code not working

I am stuck on what I am doing wrong. I get an error message when I enter the code below. I’ve tried everything from deleting spaces to adding spaces… Can anyone help me troubleshoot/point out the mistake causing this sub-course to not be accepted as right?

   **Your code so far**

h1 {
  font-size: 68px;
h2 {
  font-size: 52px;
  font-size: 40px;
  font-size: 32px;
  font-size: 21px;
h6 {
  font-size: 14px;

<h1>This is h1 text</h1>
<h2>This is h2 text</h2>
<h3>This is h3 text</h3>
<h4>This is h4 text</h4>
<h5>This is h5 text</h5>
<h6>This is h6 text</h6>

Hi @rstewart
I’ve checked your code and it works fine. Maybe refresh your browser or try using a different browser if the problem persists.
Happy coding!

Used a different browser and it worked, thank you!
