Tell us what’s happening:

Test 16 won’t pass. I believe my if else chains satisfy all conditions. But, I’m not getting why 16 doesn’t pass the checks.

Your code so far

Welcome to the forum @ultra-onyx,

If you run the tests then open up your browser’s console, you’ll see this assertion error:

That should give you an idea about where you should look to debug your code.

Happy coding
