define(n)(o
replace item((b)-((b)mod(n)))of[q v]with(o
when gf clicked
repeat(100
change[b v]by(1
add(b)to[q v
(3)[Fizz
(5)[Buzz
(15)[FizzBuzz
```
Note: This requires `b` to have the value 0 before starting (which is the default value that all variables are initialized to upon creation in Scratch), and it requires the list `q` to be blank and displayed (which are the default conditions when creating a list).
