Others have already explained to you where the problem is. On a
different note, beware of possible name clashes between scalars and
variables, even scalars and abbreviated variables names, as the
example below demonstrates. To avoid the possibility of a name clash,
you can use -tempname- for your scalars inside your programs, or use
the -scalar()- function when referring to scalars.

*** example of how not to do it
capture program drop test
program test
syntax , K(integer) L(integer)
scalar first = `k'
scalar second = `l'
scalar product = first*second
di product
end
clear
set obs 1
gen first = 111
gen second = 222
test , k(2) l(3)
rename second seconds
test , k(2) l(3)
gen product = 555
test , k(2) l(3)
