hi guys, im semi new to all this and im trying to figure out how to input a cost factor into the harvesting of the drugs? ive found the code but not sure where to go from there?
any help would be great! Thanks.

local function HarvestWeed(source)

if CopsConnected < Config.RequiredCopsWeed then
	TriggerClientEvent('esx:showNotification', source, _U('act_imp_police') .. CopsConnected .. '/' .. Config.RequiredCopsWeed)
	return
end

SetTimeout(5000, function()

	if PlayersHarvestingWeed[source] == true then

		local xPlayer  = ESX.GetPlayerFromId(source)

		local weed = xPlayer.getInventoryItem('weed')

		if weed.limit ~= -1 and weed.count >= weed.limit then
			TriggerClientEvent('esx:showNotification', source, _U('inv_full_weed'))
		else
			xPlayer.addInventoryItem('weed', 1)
			HarvestWeed(source)
		end

	end
end)

end
