Hmm, I'm not sure why that didn't work. You can add a fallback value to a variable by putting it as the second value of where you use the variable like this: `var(--variable-name, fallback-value)`. The property will use the fallback value when there's a problem with the variable. Add a fallback value of `green` to the `background-color` of `bb2`.
