Learn Basic Algorithmic Thinking by Building a Number Sorter - Step 5

Tell us what’s happening:

The step is asking me to Use document.getElementsByClassName() to get all the elements with this class by passing in the argument “values-dropdown”. Assign that to an inputValues variable with const.

which I already did, But tests are still not passing

Your code so far

Your solution works from my end. Please try one of the following steps to move forward.

Click on the “Restart Step” button and force a refresh of your page with CTRL + F5 then try to paste the code in again.

or - Try the step in incognito or private mode.

or - Disable any/all extensions that interface with the freeCodeCamp website (such as Dark Mode, Ad Blockers, or Spellcheckers), and set your browser zoom level to 100%. Both of these factors can cause tests to fail erroneously.

or - Ensure your browser is up-to-date or try a different browser.

I hope one of these will work for you.

I think it was a temporary error, because it works now without changing anything.
