We need to see your code, not a link to the challenge you are working on.

* * *

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (`</>`) to add backticks around text.

 ![Pre-formatted-text](https://global.discourse-cdn.com/freecodecamp/original/3X/1/b/1b18854f1059217f29370444396145cc3a0cd8ae.gif)

See [this post](https://forum.freecodecamp.org/t/forum-code-formatting/25574) to find the backtick on your keyboard.  
**Note:** Backticks (`) are not single quotes (’).

I believe that you may be missing a division operation in there.

I’m not sure if you fully understood the code you wrote. Can you describe, in words, what your code is doing? If you can describe your code, line by line, in words, then you will be able to see where you need to divide two quantities.
