I stumbled across this NPC that sells spells. And i have attempted to change it a couple times but no luck. I want the NPC to offer 2 spells and the person can only choose one. Is it possible?
Lua: 
local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)

local talkState = {}
function onCreatureAppear(cid)                 npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid)             npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg)         npcHandler:onCreatureSay(cid, type, msg) end
function onThink()                             npcHandler:onThink() end

Take the two spells out of spells and at the top put:
Code: 
 local specialspells = {
    [spellid1] = { buy = 80, spell = "spellname1", name = "Level 008: spell name", vocations = {1,2,3,4,5,6,7,8}, level = 8, premium = 0},
    [spellid2] = { buy = 80, spell = "spellname2", name = "Level 008: spell name", vocations = {1,2,3,4,5,6,7,8}, level = 8, premium = 0}
    }
and instead of,
Code: 
    if msgcontains(msg, 'spells') then
        npcHandler:say("Here are the spells that you can learn from me.", cid)
        for var, item in pairs(spells) do
            if (not getPlayerLearnedInstantSpell(cid, item.spell) and getPlayerLevel(cid) >= item.level and isInArray(item.vocations, getPlayerVocation(cid)) and (item.premium == 1 and PremiumSpells == TRUE or item.premium == 0)) or AllSpells == TRUE then
                table.insert(shopWindow, {id = var, subType = 0, buy = item.buy, sell = 0, name = item.name})
            end
        end
        openShopWindow(cid, shopWindow, onBuy, onSell)
    end
put:
Code: 
   if msgcontains(msg, 'spells') then
        npcHandler:say("Here are the spells that you can learn from me.", cid)
        for var, item in pairs(spells) do
            if (not getPlayerLearnedInstantSpell(cid, item.spell) and getPlayerLevel(cid) >= item.level and isInArray(item.vocations, getPlayerVocation(cid)) and (item.premium == 1 and PremiumSpells == TRUE or item.premium == 0)) or AllSpells == TRUE then
                table.insert(shopWindow, {id = var, subType = 0, buy = item.buy, sell = 0, name = item.name})
            end
        end
        if not cid:hasLearnedSpell(spellname1) and not cid:hasLearnedSpell(spellname2) then
            for var, item in pairs(specialspells) do
                if (not getPlayerLearnedInstantSpell(cid, item.spell) and getPlayerLevel(cid) >= item.level and isInArray(item.vocations, getPlayerVocation(cid)) and (item.premium == 1 and PremiumSpells == TRUE or item.premium == 0)) or AllSpells == TRUE then
                    table.insert(shopWindow, {id = var, subType = 0, buy = item.buy, sell = 0, name = item.name})
                end
            end
        end
        openShopWindow(cid, shopWindow, onBuy, onSell)
    end
should work.
Now, once they have learned either one of the spells neither of them should appear in the shop window, which is what you wanted right?

Yes, thank you. I'm on vacation currently for the next week. But once I get home I'll give it a test, and if I have any issues or questions I'll shoot you a message. Thanks for the help!
