[LUA] How npc can execute "commands"?

[Gesior.pl]

Is it possible to make NPC who will 'kick' (/kick "name") players?

	if msgcontains(msg, 'kickme') then
	selfSay('/kick ' .. getPlayerName(cid) .. '')
	end

doesn't work
NPC only say "/kick Sorcer" :/

Try set in NPC file "access" to highter.

 

[Gesior.pl]

<npc name="Jeremiasz" script="data/npc/scripts/jeremiasz.lua" autowalk="1" floorchange="0" access="5">

Good? It doesn't work. Still say "/kick Sorcer"
EDIT:
If someone have same problem use:

if msgcontains(msg, 'kickme') then
doRemoveCreature(cid)
end

It's code from my NPC.
