Hi,

Your problem is that local variables are not accessed via function's 
environment. You have to use the debug library to do so:

function foo( a, b )
    local z = a + b
    bar()
end

function bar( )
    print( debug.getlocal( 2, 1 ) ) --> a	4
    print( debug.getlocal( 2, 2 ) ) --> b	5
    print( debug.getlocal( 2, 3 ) ) --> z	9
    print( debug.getlocal( 2, 4 ) ) --> nil
end

foo( 4, 5 )



Please refer to Lua's documentation about debug.getlocal (and it's 
friends: debug.setlocal and debug.getinfo)
