Hey there,

nice to meet you! :wave:

Do you talk about a Project?

Then you have to add the code for the tests into the HTML box on the left side and on the right side you will see a box where you have to choose the project.

There is an error in the browser console when loading the freecodecamp javascript from the CDN:

Uncaught TypeError: Cannot read property 'appendChild' of null
    at Module.<anonymous> (bundle.js:657)
    at r (bundle.js:1)
    at bundle.js:1
    at bundle.js:1

The tests popup menu was not appearing in codepen because the browser was blocking third party cookies and popups. The browser console error above was fixed by moving the following code to the bottom of the <body> tag: <script src="https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js"></script>
