I have the following code, and it is not working. Why is this?
```julia
s = 0
for i = 1:2
s += i/2
end
```

You haven’t read the scope docs!
```julia
s = 0
for i = 1:2
global s += i/2
end
```
Note that this is a controversial new feature of 1.0: [https://github.com/JuliaLang/julia/issues/28789](https://github.com/JuliaLang/julia/issues/28789)

You should be able to mark a post as “Solved”, so people don’t waste time looking at it.
