Lua Npc's problem

[Faraonekkk]

the problem is
me: hi
npc: hiho
me: sell mace
npc: error in console

data/npc/scripts/lib/npcsystem/modules.lua attempt to call global 'GetItemPlural' <a nil value>

my ItemPlural in modules.lua

if(parameters.eventType == SHOPMODULE_SELL_ITEM) then
local msg = module.npcHandler:getMessage(MESSAGE_SELL)
msg = module.npcHandlerarseMessage(msg, parseInfo)
if(module.amount>1) then
module.npcHandler:say(' Do you want to sell ' .. module.amount .. ' ' .. GetItemPlural(getItemIdByName(tmpName)) .. ' for ' .. parameters.cost*module.amount .. ' gold coins?')
elseif tmpName:sub(1,1):upper() == "e" or tmpName:sub(1,1):lower() == "y" or tmpName:sub(1,1):lower() == "u" or tmpName:sub(1,1):lower() == "i" or tmpName:sub(1,1):lower() == "o" or tmpName:sub(1,1):lower() == "a" then
module.npcHandler:say(' Do you want to sell an ' .. tmpName .. ' for ' .. parameters.cost*module.amount .. ' gold coins?')
elseif GetItemPlural(getItemIdByName(tmpName)) == tmpName then
module.npcHandler:say(' Do you want to sell ' .. tmpName .. ' for ' .. parameters.cost*module.amount .. ' gold coins? ')
else
module.npcHandler:say(' Do you want to sell a ' .. tmpName .. ' for ' .. parameters.cost*module.amount .. ' gold coins?')
end
elseif(parameters.eventType == SHOPMODULE_BUY_ITEM) then
local msg = module.npcHandler:getMessage(MESSAGE_BUY)
msg = module.npcHandlerarseMessage(msg, parseInfo)
if(module.amount>1) then
module.npcHandler:say(' Do you want to buy ' .. module.amount .. ' ' .. GetItemPlural(getItemIdByName(tmpName)) .. ' for ' .. parameters.cost*module.amount .. ' gold coins?')
elseif tmpName:sub(1,1):upper() == "e" or tmpName:sub(1,1):lower() == "y" or tmpName:sub(1,1):lower() == "u" or tmpName:sub(1,1):lower() == "i" or tmpName:sub(1,1):lower() == "o" or tmpName:sub(1,1):lower() == "a" then
module.npcHandler:say(' Do you want to buy an ' .. tmpName .. ' for ' .. parameters.cost*module.amount .. ' gold coins?')
elseif GetItemPlural(getItemIdByName(tmpName)) == tmpName then
module.npcHandler:say(' Do you want to buy ' .. GetItemPlural(getItemIdByName(tmpName)) .. ' for ' .. parameters.cost*module.amount .. ' gold coins? ')

module.npcHandler:say(' Do you want to buy a ' .. tmpName .. ' for ' .. parameters.cost*module.amount .. ' gold coins?')

If i put in GetItemPlural GetCount or GetItemName everything is okay but its not reading "Sellable shop" ;/

its making me crazy i am tired of this.

 

[Faraonekkk]

i see more now
i puted into my npc functions

function getItemPluralNameById(itemid)
return GetItemDescriptions(itemid).plural
end

but i have error in console with this line:

return GetItemDescriptions(itemid).plural

attempt to call global 'GetItemDescriptions' <a nil value>

also checked sources there is something like "GetItemDescriptions" function

 

[Faraonekkk]

compiled function

getItemDescriptionsById

, also added it to npc functions and its workin BUT i can only buy items its not getting if i write SELL. ;/

sellable items is in XML and buyable in script .lua (NOTE: engine is for 7.6- version )

atm for sure i need compile to check sell from xml any idea?
