[Zolax]

Hello I have a problem. When i sell items in npc he gives me money but they arent together. How i can solve it? Here is example of my npc:

_state = 0
_count = 0
_index = 0
_delay = 500

items = {}
--runes
items[0] = {name = 'white pearl', id = 2143, subtype = -1, sell = 0, buy = 160}
items[1] = {name = 'black pearl', id = 2144, subtype = -1, sell = 0, buy = 280}
items[2] = {name = 'small diamond', id = 2145, subtype = -1, sell = 0, buy = 300}
items[3] = {name = 'small sapphire', id = 2146, subtype = -1, sell = 0, buy = 250}
items[4] = {name = 'small emerald', id = 2149, subtype = -1, sell = 0, buy = 250}
items[5] = {name = 'small ruby', id = 2147, subtype = -1, sell = 0, buy = 250}
items[6] = {name = 'small amethyst', id = 2150, subtype = -1, sell = 0, buy = 200}
items[7] = {name = 'wedding ring', id = 2121, subtype = -1, sell = 0, buy = 100}
items[8] = {name = 'scarab coin', id = 2159, subtype = -1, sell = 0, buy = 100}






local function onActionItem(action)
	if ((action == 'buy' and items[_index].sell == -1) or
		(action == 'sell' and items[_index].buy == -1)) then
		return 
	end
	
	amount = ''
	suffix = ''
	plural = 'a'
	
	if (_count > 1) then
		amount = ' ' .. tostring(_count)
		suffix = 's'
		plural = ''
	end
	
	cost = items[_index].buy
	if (action == 'buy') then
		cost = items[_index].sell*_count
	else if(action =='sell') then
		cost = items[_index].buy*_count
	end
	end
	
	selfSay('Do you want to ' .. action .. ' ' .. plural .. amount .. ' ' .. items[_index].name .. suffix .. ' for ' .. cost .. ' gold?')
