Hello,

I have a function which follows the condensed, simplified format shown below.

```
using Statistics: std, mean, median, var
function foo(a,b,c)
"""
Do some stuff
"""
if a > 0
if a == 1
bar(x) = std(x, corrected=false)
elseif a == 2
bar(x) = var(x, corrected=false)
elseif a == 3
bar(x) = mean(abs.(x .- mean(x)))
elseif a == 4
bar(x) = median(abs.(x .- median(x)))
end
else
"""
Do some other stuff instead
"""
end
return c*bar(b)
end
```

When I call the `foo`

function for `a = 0`

or `a = 1`

, it runs fine.

However, for `a > 2`

an error message appears for an undefined variable:

`ERROR: UndefVarError: bar not defined`

Each of these `bar`

functions runs normally when called in the REPLâ€¦

Can anyone tell me why I might be getting this error for `a`

values greater than 1?

Thanks for your help
