Help with NPC

[Dankoo]

I have the following function on my Killing in the name of NPC:

local rank = {
			[1] = {need_points = 5, storage_value = -1, talkstate = 50},
			[2] = {need_points = 10, storage_value = 0, talkstate = 51},
			[3] = {need_points = 20, storage_value = 1, talkstate = 52},
			[4] = {need_points = 30, storage_value = 2, talkstate = 53},
			[5] = {need_points = 50, storage_value = 3, talkstate = 54}
			}

for i = 1, #rank do
	if msgcontains(msg, 'rank') then
		if points >= rank[i].need_points and promote == rank[i].storage_value then
				if rank[i].need_points == 5 then
					selfSay("Welcome back "..getCreatureName(cid)..". You have completed 5 tasks for our society. Ask me for a {promotion} to advance your rank!", cid)
				elseif rank[i].need_points == 10 then
					selfSay("Welcome back "..getCreatureName(cid)..". You have completed 10 tasks for our society. Ask me for a {promotion} to advance your rank!", cid)
				elseif rank[i].need_points == 20 then
					selfSay("Salutations "..getCreatureName(cid)..". You have completed 20 tasks for our society. Ask me for a {promotion} to advance your rank!", cid)
				elseif rank[i].need_points == 30 then
					selfSay("Welcome back "..getCreatureName(cid)..". You have completed 30 tasks for our society. Ask me for a {promotion} to advance your rank!", cid)
				elseif rank[i].need_points == 50 then
					selfSay("By the gods....50 hunting tasks....this is austoding! Ask me for a {promotion} to advance your rank! And while you are here, I also have another special task for you.", cid)
				end
			talkState[talkUser] = rank[i].talkstate
		end
	end
end

What does it do:
When you have completed X tasks, he says the above sentences

What I would like it to do:
When you say "rank", it says your current rank

Any ideas about what might work?

Thanks! eace:
