levelsof within for loop

[Chun Kit Dai]

I am using STATA 17 and want to run the following code

* for each block
forvalues b = 1/`nblock' {
levelsof choice_set if block == `b', local(choice_sets)
* for each choice set
foreach c_set in local choice_sets {
display `c_set'
}
}

I ran into an error `local not found`
Not sure what went wrong, I went through the post "levels of loop within a loop" by Peggy Fan in 2014. It doesn't seem to be working

Appreciate any help and suggestions! Thank you

foreach c_set of local choice_sets

foreach lname in list { ... } allows a general list. Elements are separated from each other by
one or more blanks.

foreach lname of local list { ... } and foreach lname of global list { ... } obtain the list
from the indicated place. This method of using foreach produces the fastest executing code.
