brilliant. The line
local lags
is exactly what was needed to make it work. It is now doing exactly what I want it to do.
Many thanks for your help.

You would need to blank out the macro
once in each loop:
foreach k of varlist netprem disclm elr solv {
preserve
keep if variable == "`k'"
local lags
forvalues x = 1/19 {
sum lagrawnotrend if comcode == `x', mean
local lags "`lags' `r(mean)'"
}
levinlin `k', lags(`lags')
restore
}
