st: question about local and var[n]

Dear all,
I have one question about the use of local macros.
For example, assume the date
ID ny_price
ny 5
wa 4
set obs 2
gen str ID=""
replace ID="ny" in 1
replace ID="wa" in 2
gen ny_price=4
replace ny_price=5 in 1
Then My question comes from the following differences:
. local city ny
.
. replace `city'_price=100 in 1
(1 real change made)
However,
. local city ID[1]
. di `city'
ny
. replace `city'_price=100 in 1
weights not allowed
r(101);
Why?
thanks!
