Good job! 

Just a minor detail about the coding style, you need to use the following form that connects multi-line blocks:
```
if any [
    ...
][
    ...
]
```

This form will be part of the standard Red coding style because it creates a single "blank" line instead of two (we care about the number of significant lines of code). It also has the big advantage of being able to copy/paste it in a Red console, while the two-lines form (closing and opening brackets on different lines) will create an error when pasting in the console.
