right, this assigns a new table to rt[var].

try rt[var][pa2]=va2 to set more values in the existing table.

to set multiple values in rt[var] one would use:

if not rt[var] then rt[var] = {} end
local t = rt[var] -- now is the same table, not a copy
t[pa1]=va1 -- thus values go to rt[var]
t[pa2]=va2
